CANSAT A CanSat is a type of sounding rocket payload used to teach space technology. It is similar to the technology used in miniaturized satellites. No CanSat has ever left the atmosphere, nor orbited the earth. In CanSat competitions, the payload is required to fit inside the volume of a typical soda can (66mm diameter and 115mm height) and have a mass below 350g. Antennas can be mounted externally, but the diameter can't increase until the CanSat has left the launch vehicle. The CanSats are deployed from small rocket at height which varies depending on the competition. CanSats are equipped with a recovery system, usually a parachute, to limit damage upon recovery and to allow the CanSat to be reused. CanSats are used to teach space technology, beca use of their inexpens ive price and small volume.

TYPE OF CANSAT Telemetry This is the one whose primary purpose is to collect and transmit data from the flight and weather conditions in real time to be processed by a ground station. CanSats in this category do not use a steering system since its objective is not to fall at a particular point but to collect data while the descent (which is not usually controlled). Of the systems mentioned in the previous sections the most used are: barometer, thermometer, GPS and camera.   --------------------------------------------------------------------- Comeback The main task of these is to land in a controlled manner as close as possible to a target marked by GPS coordinates. These devices can be guided by GPS or by and Inertial Navigation System INS. This position is sent to the microprocessor which compares the position of the target from the analysis of these data to calculate the angle at which it should turn to address the target and gives appropriate instructions to the steering system...

HISTORY OF CANSAT In 1998, about 50 students and faculties from 12 universities from the United States and Japan met at a symposium held in Hawaii. It was the first "University Space Systems Symposium". Here, Bob Twiggs, professor emeritus at the Stanford University, proposed the initial idea of what later would become the nanosatellite projects.[3] That idea was to launch a structure of the size of a soda can into space. Its volume should be around 350 milliliters and the mass, about 500 grams. This led to a project that began in 1999 called ARLISS, involving mostly American and Japanese Universities, carrying out the first launch on September, 11th of that year and continuing each year without interruption.The initial idea, still prevalent today, was to launch 3 satellites of 350 milliliters, or a satellite of greater volume. The means would be a rocket capable of moving 1.8 kilos and of ascending to 4000 meters, opening the door to low cost space flights -about $400.[4] In...
