The CICERO model was prominently featured at the booth. ANTELSAT Brochure http://iie.fing.edu.uy/investigacion/grupos/lai/files/ ANTELSAT_brochure_2012W01.pdf. Q: Does the attitude determination and control system rely solely on reaction wheels? The cube is slated for a 2013 launch. A spacecraft system comprises various subsystems, dependent upon mission profile. Quebec, there was a negative telemetry lock - they could not communicate with the spacecraft. 1) Rapid autonomous commissioning – It is planned to demonstrate advanced autonomous commissioning techniques, including new attitude determination and control and detumble technologies. During a later pass it was determined that Radarsat-1 was in a "Safe Hold" mode - an automatic mode it places itself in when something goes wrong. (2) In-orbit approach and inspection – It is planned to demonstrate miniature JPEG imagery, short videos etc.) to be downlinked by other users. BEESAT-1 Engineering Qualification Model. The functions of a regular satellite would be partitioned in a System F6 model, with the power, receiver, control, computing, payload functionality and ground communication capabilities housed in separate modules. Pitch wheels are spinning weighted metal wheels inside the spacecraft which help to control its attitude or position in space. Attitude control: - Attitude determination via magnetometer and photodetectors. €�The PhoneSat project is kind of a technology demonstration effort,” said Jasper Wolfe, technical lead for attitude determination and control of the launch vehicle for the PhoneSat Project at NASA Ames. More information about this spacecraft is available from its maker, Surrey Satellite Technology, Ltd. With many backup systems, but until now, few have been needed. - Active 3-axis control via magnetorquers. The Berlin Experimental and Educational Satellite 2 is a 1U CubeSat project intended to test a reaction wheel and an Attitude Determination and Control (ADC) system. How do The flight software has a look up table that it uses to determine the spacecraft position, this table is updated through TLE data. Prior to the NSS, the CICERO structures team was hard at work designing and supporting fabrication of a 1/2 scale model of the CICERO spacecraft. CICERO 1/2 Later in April, our Attitude Determination & Control Lead and his colleague traveled to Berlin, Germany for vendor visits, including Vectronic and Astro- und Feinwerktechnik. ANTELSAT is a 2U CubeSat class satellite with a 70 cm SSTV downlink and amateur radio AX.25 Digipeater that is planning a Yasny Dnepr launch in 2013.
