Cartosat-2B

Cartosat -2B is an Indian earth observation satellite from the Indian Remote -sensing range.

Details

Cartosat -2B is used to supplement the technically very similar Cartosat -2 and Cartosat -2A and to serve the creation of large-scale maps and continue to support the urban and infrastructure planning. The launch took place on July 12, 2010 at 05:52 CEST clock with the PSLV - C15 rocket from the Satish Dhawan Space rocket launch site from Centre, the PSLV was not equipped with this start with boosters. The satellite was suspended after 1034 seconds at an altitude of around 637 kilometers above the earth's surface in a circular sun-synchronous orbit with an inclination of about 98.1 °. Then, also of the 116 kg Alsat -2A Algerian Earth observation satellite was separated and finally the three nano or pico Studsat from India, AISSat -1 exposed from Norway and TIsat -1 from Switzerland.

Studsat is a 10 x 10 x 13.5 cm high, 650 g heavier cube built by students from seven universities in the Indian cities of Bangalore and Hyderabad and carrying a CMOS camera with a resolution of 90 meters. For the communication to the satellite ground station, called a special NASTRAC was established. NASTRAC stands for Nitte Amateur Satellite Tracking Centre, according to the station in Nitte Meenakshi Institute of Technology is housed. The life of six months can be expected.

AISSat -1 is 6.5 kg and was difficult ( forskningsinstitutt Forsvarets ) at the Laboratory for Space Flight at the University of Toronto (SFL, Space Flight Laboratory) for the Norwegian defense research institute FFI built. With its help, you want to test whether a stationed in space for the recipient of vessels of more than 300 gross tons to be broadcast AIS signals can effect improvements in the control of vessel traffic in the far north. The lifetime of the satellite is given as three years. The total cost of the project is estimated at around 30 million Norwegian kroner, converted are about 3.7 million euros. June 1, 2010 is already another Norwegian AIS test payload went into operation in space. The Norwegian AIS receiver ( NORAIS ) is housed in the European Columbus module of the International Space Station, an associated antenna system is mounted on the outside Columbus.

TIsat -1 is a student training serving picosatellite of southern Switzerland University of Applied Sciences universitaria Scuola della Svizzera italiana professional ( SUPSI ) and an amateur radio satellite. It is used in materials science and technology and testing to determine, among other things, the time that elapses until the space conditions exposed thin metal wires and connections on circuit boards have interruptions. Of the cube-shaped satellite has a mass of about one kilogram, and an edge length of about 10 centimeters. He also radiates radio call sign of the gemorste HB9DE than identification.

Specifications

Cartosat -2B is equipped with a panchromatic camera that delivers images in the spectral range between 500 and 850 nanometers, with a swath width from 9.6 to 290 km and a resolution of about 0.8 m. The three -axis stabilized satellite can to make recordings to ± 26 ° out of the orbital plane and thus absorb a given area stereoscopically and additionally more often than pure vertical view direction. The data are stored on a 64 GB solid state disk and transmitted at a data rate of 105 MBPS to Earth. The power of the satellite is carried out by two solar cells boom which can generate an electric power of 930 watts. To store the electrical energy of the satellite is equipped with two nickel - cadmium batteries with a capacity of 18 amp-hours. For the stabilization and trajectory correction he is with star sensors and gyros with Reaction Wheels, Magnetic torquers and hydrazine thrusters. Controlled and monitored, he is from India ISTRAC, there are ground stations at Bangalore, Lucknow and Mauritius, Biak in Indonesia, in Tromsø and on Svalbard in Norway and in the Troll research station in the Antarctic for use. The planned life of the satellite is five years.
