All 7 satellites launched in their precise orbits by ISRO’s old workhorse, the PSLV in its 16th launch is indeed praiseworthy. The successor to the Oceansat-1, is supposed to be the country’s second ocean studies satellite that aims to aid fishermen in identifying fishing zones and weathermen to forecast cyclones by measuring sea surface winds.
Along with the Oceansat-2, 6 nano satellites (4 CUBESATS and 2 RUBIN) were also launched.
CUBESATs : The four CUBESATs are educational satellites from European universities, each weighing around one kg. and developed to perform technology demonstration in space. The satellites are launched inside a Single Picosatellite Launcher (SPL) also weighing one kg., which is a dedicated European launch adaptor to deploy a CubeSat.
CUBESAT-1: UWE-2, from the Universität Würzburg, Germany
UWE-2 is a pico satellite, with the mission objective of demonstration of a newly developed Attitude Determination and Control system (ADCS) and the technology demonstration of a GPS on a Cubesat.
CUBESAT-2: BeeSat, from the Technische Universität Berlin, Germany
BeeSat is a pico satellite project of the Technical University of Berlin with the main objective of on-orbit verification of newly developed micro reaction wheels for pico satellite applications and will demonstrate the use of coin sized micro reaction wheels for attitude control of pico satellites in orbit as one of the key elements
CUBESAT-3: ITU-pSAT1, from Istanbul Technical University, Turkey
The primary mission of the satellite is to examine the performance of an on-board passive stability system consisting of a magnet which will align the satellite to the magnetic field of the Earth with an error of about 15 degrees according to simulations, and to verify this figure. A secondary objective is to download photographs taken using a camera with a resolution of 640 x 480 pixels
CUBESAT-4: SwissCube, from Ecole Polytechnique Fédéral de Lausanne, Switzerland
The SwissCube mission objective is to house a science payload and take optical measurements and characterize the airglow intensity over selected latitudes and longitudes thereby demonstrating that the airglow emissions are strong enough to be measured by an off-the-shelf detector and validating the concept for the development of a low-cost Earth sensor.
RUBIN-9 consists of two Spacecrafts Rubin-9.1 and Rubin-9.2 weighing 8kg each and will primarily be used for the Automatic Identification System (AIS) for Maritime applications. These are non-separable payloads that will be mounted at an angle of 45deg to the PSLV EB deck.
Rubin-9.1 is developed by Luxspace and has a mission objective of providing an insight into the issue of message collisions that limit detection in areas of dense shipping.
The main purpose of the Rubin-9.2 spacecraft is to test and qualify nano technologies from Angstrom company Sweden and to continue space based maritime Automatic Identification System (AIS) receiver experiments (started with Rubin-7 and Rubin-8 missions). Rubin-9.2 is similar to the Rubin-8 launched on PSLV-C9 in April 2008.
