||Concerns for end-to-end solutions for maritime security using AIS satellites
||The Indian peninsular has a coastline that runs for about 7,517 Km, being the largest country in South Asia. The large coastline accommodates for trade along major ports such as Mumbai, Mangalore, Chennai, etc. With this the concern for maritime security takes priority for both goods on-board vessels as well as in-land security. AIS based on Small Satellites are an excellent solution to keep track of ships and smaller vessels in-and-around the coastline and within deep sea moving towards the coastline. However, only cooperating vessels broadcast AIS information and the threat vessels may not carry a transponder or broadcast any information. Non-cooperating vessels away from ground-based radars have very less probability of identification. AIS solution providers will hence provide an incomplete end-to-end solution for maritime tracking with no information being collected on non-cooperating vessels, which are out of range of ground based tracking systems. Hence, AIS constellation designers and service providers must engage on technological solutions for tracking non-cooperating vessels, preferably using coordinated terrestrial systems onboard ships and space based systems.
|U-2||MITIGATION OF OIL PIPELINE VANDALIZATION USING SMALL SATELLITE
||Oil pipeline vandalization is an illegal act of destroying or puncturing of oil pipeline so as to disrupt supply and siphon crude oil or its refined product for personal use. This has led to shortage of petroleum product for end users, loss of life as a result of accompanied fire outbreak, pollution of aquatic life and food crises in the nation.|
Recent studies show that Nigerian government loses billions of dollars as a result of the activities of these vandals on the pipelines. In previous years, the main measure taken by the Nigerian government to guard against these activities had been to deploy security personnel to some of the areas that are prone to attack by intruders. However, in more cases than not, this step had failed to significantly ameliorate the problem.
This paper is aimed at proposing an alternative approach to resolving the challenge of oil pipeline vandalism, using space-based system (small satellites) in the Low Earth Orbit.
|U-3||6S Initiative (Satellites - Schools - Science - Simple - Space – Students)
||Many people technology enthusiasts, students and professionals in electronics, telecommunications and IT, would like to have experience with satellites from tracking stations in their homes or schools.|
Receive and transmit signals to a satellite requires specific knowledge in antennas, transceivers, orbital parameters and other information that are only available to radio amateurs or experts in telecommunications satellite. The proposed concept is a global network of friendly access to satellites intended for persons not expert in SATCOM. The project consists of three distinct segments.
I) A small transponder to be embedded in scientific satellite, technological governmental or private wishing to collaborate with the program.
II) A friendly Ground Station, with some key capabilities
a) Easy user installation on the roof.
b) Ability to auto tracking satellite using mechanical servo or phase array antennas.
c) USB interface with a conventional PC.
d) Costs compatible with a tech gadget, like a notebook or tablet.
e) Plug and play philosophy
III) A web service with information about the satellites available and how to access them.
The main applications of the project would be:
Text messages between stations.
Beacon localization experiments.
Estimates of orbital parameters and vehicle dynamics experiments
Up load data from micro weather stations (or another sensor package) connected on stations.
Receiving some parameters of satellite telemetry.

||Microgravity Experiment Recovery Satellite (MERS)
||Current long duration microgravity experiments that require the recovery of the experiment for analysis are restricted to competing for limited space and time on the International Space Station (ISS). This has slowed the progress of scientific research due to high costs, wait times, and lack of access. A micro-satellite designed to be reusable and recoverable that can carry scientific payloads from orbit safely back onto the ground will be a leap forward in micro-gravity research. This mission will aim to prove the concept of a recoverable orbiting micro-lab. To prove this concept, our initial mission must complete two primary goals. First, design a clever platform that minimizes the mass of the main systems in order to allow the largest experimental payload possible. Second, design a test experiment that gathers flight dynamics and records other data such as thermal, telemetry, vibration, and radiation conditions for analysis of launch and reentry.|
In the end, the objective of this program is to develop and verify the technology for a recoverable microsat capable of performing micro-gravity experiments in low-earth orbit. This technology will allow for many areas of material science, biology, and engineering to be expanded by the increased availability of long duration microgravity experimentation.
|U-6||Monitoring Natural Disasters with Small Satellites
||Natural disasters are happening all over the world; they can happen anywhere and anytime. Different organizations operate before, during and after the crises events aiming to alert, monitor and estimate the impact. Real damage evaluations after the disaster allow verifying and improving model calculations. Satellite images have increased the ability to assess and predict natural hazards to prevent properties, infrastructure and human lives. There have been a number of satellites and sensors that have changed the way we assess and predict natural disasters. These sensors are able to quantify geophysical phenomena associated with natural hazards.|
Significant improvements in the availability of near real-time assessments of natural hazards have been made due to increases in data acquisition rates, sensor resolution, improvement of change detection algorithms, and integration of remote sensing systems. However there is still a need to develop a cheap and agile satellite system or a constellation of them to observe natural hazards. Small, i.e. micro- and nano-satellites are especially promising since they are reaching the capabilities needed to map natural disasters, especially high spatial resolution, good spectral resolution and very good revisit/imaging times.
||PHASES: ultra-precise absolute flux spectroscopy of stars from space
||Absolute flux spectroscopy is key to accurately determine stellar properties, which has an impact in many Astrophysical fields. Ground-based observations are limited by Earth's atmosphere scintillation noise, day-night cycle, and variable weather conditions. A space-borne instrument obviates these issues, improving photometric precision by approx. 1000 times. PHASES, a 20-kg telescope, is proposed to attain absolute flux spectroscopy from a microsatellite at reasonable cost. The optical (370-960 nm) spectrophotometer will obtain time series of accurate flux calibrated spectra in ≤ 1min integration time of bright stars (V≤10) and measure photometric variations with unprecedented precision (approx. 1 part per million). Detailed studies of active and exoplanet-host stars can be performed. In particular, stellar and planet radii will be determined with precisions better than 1%. The main technical challenges are to avoid stray light and achieve high pointing stability. Stray light is limited with the use of a compactly folded, quasi-baker type, off-axis three mirror, 20-cm aperture telescope. A high pointing stability of 0.2 arcsec (goal: 0.1 arcsec) for observing periods lasting over several weeks is achieved by using an integrated star sensor camera. This requires a microsatellite that should incorporate accurate attitude control actuators to work in combination with the star tracker system.
||EXPERIMENTAL ANALYSIS OF SATELLITE THERMAL CONTROL SYSTEM BY SALINA AND ELECTROMAGNETIC PULSE COOLING
||Currently the satellites are versatile and sophisticated, there is already passive thermal regulation system in, which is conformed with static elements and through geometry, materials, coatings and size dimensions regulates the inside temperature and protects the artificial satellite, there is also a dynamic temperature control system with moving elements such as turbines, fans and heat exchangers working with refrigerant gases.|
The first configuration of the thermal regulation system is to place over the satellite outer surface a vacuum insulating film, which is formed from many layers of aluminum which also may incorporate thin fiberglass layers. It is necessary the incorporation of a satellite active control system to recirculate the working refrigerant (a fan or pump in a closed circuit).
It is possible to reduce the diameter of the cooling tubes by the addition of salts inside the cylinders assuming that the system must be completely sealed and pressurized; also it must be considered a zinc coating to prevent corrosion. In this kind of configuration is included a coolant which changes from solid to liquid when it is exposed to extreme temperatures.
The second configuration of the thermal regulation system is the test of an electromagnetic system which produces electrical pulses to refrigerate the satellite structure. Electric current pulses passes through an electrical resistance, heat will be absorbed by the electromagnetic wave cooling the wall where the resistance is placed.
||Accident Tracking and signal transfer Satellite In Nigeria
||It has been estimated that about 1.4million people dies on road accident every year around the world. Another one million death; is believed to be caused by other forms of transportation in the world yearly which include rail, ship and airplanes e.t.c. In Nigeria, about 5000 death is estimated to be caused by road accident; while another 4500 other death is believed to be caused by other forms of transportation on yearly bases. If you sum this up, you will get 9500 death which is attributed to accident alone in Nigeria. Most of this death is not as a result of the immediate accident but as a result of the absence of rescue team who could move these victims to hospital for immediate medical attention.
||Utilizing Nano Satellites for water monitoring for Nile River
||Many countries today utilize the technology of Nano satellites for water monitoring of seas or rivers. Yet none of the ten governorates, that the Nile River pass by which is the longest river all over the world, haven't made use of this technology till now.
Utilizing Nano satellites for water monitoring of Nile River is the optimum solution for many problems which based on three angles the first is management conflict for share water between Nile basin countries, the second, most of the river’s water quality is within acceptable levels, yet there are several hot spots mostly found in the irrigation canals and drainages. Sources of pollutants are from agricultural, industrial, and household waste. The third one, the locations where the water current is high will be determined which can help to generate electricity.
A satellite constellation will be used to collect data from field ground stations built near the water resources and send the acquired data to a central database which is accessible on the Internet by related agencies and individuals.
One of the major milestones is the political decision for Nile basin countries to co-operate, as well acquiring the basic know of implementing such project since the space development in the third world countries is very destitute.
||Nano-Satellite Constellation Infrastructure Concept for Various Data Acquisition Missions
||We introduce a concept of Nano-satellite constellation infrastructure that will allow any individual to transmit and receive sensory data in real-time without the need for owning and launching a designated private satellite for every individual or mission. This will allow a worldwide real-time data acquisition services besides the creation of hundreds of missions through the same system making it easier to start immediately and cutting manufacturing and launching costs to zero thereafter. All the services will be available commercially for private, governmental and institutional sectors. As an example to show the capabilities of our system, we target pollution monitoring to be an example for a mission. The users will be able to access this system by getting a low cost ground station kit and a user's interface software that will permit them to share, acquire, discuss and exchange information and sensory data with this public community.
||A Pesrsonal SpaceLab by Cubesats for space environment experimentation
||Simulating space environments such as vacuum or micro gravity require expensive and complex equipments to simulate on Earth. Thus, it is advantageous to experiment such experiments in space systems.
Currently, most of the microgravity and vacuum experiments done in space is done onboard the International Space Station (ISS). However, due to the available space and risk of the system and crew, the scope of experiment that can be done is constrained. Experiments such as combustion or hazardous events such as an occasion of fire in a spacecraft can expose the whole spacecraft in danger. Thus, there is a need for the development of an isolated system that has low risk of failure. Cubesats, for their Short development time and cost, can be built as personal experimental laboratory.
