Objectives
The main objective of his contract is to develop a set of new functions for the existing TCR transmitter product, as described in the features section. Different customers have demanded these new functions.
Challenges
The new TCR transmitter with its advanced features will answer to the demand of a larger number of potential European and American customers.
Plan
The plan is to develop partial breadboards to validate the different improvements individually, so that later they get combined in a single EQM design. This EQM is qualified against an envelope of the requirements from the most common satellite platforms, namely Alcatel/Thales, Astrium Eurostar, and Space Systems/Loral, comprising performance and environmental requirements.
Current Status
Qualification has been successfully achieved via the agreed qualification campaign, with the following environmental tests:
- Vibration:
- Low Level Sinus: a 2000 Hz, 0.5g , 2 octave /minute. Direction X,Y, Z axis. One up
- High Level Sinus:
- Random Vibration
- Shock
- Thermal Environment
| Frequency (Hz) | Acceleration (g) |
| 200 | 52 |
| 4000 | 4200 |
| 10000 | 4200 |
| Operating for Qualification | -25°C /+70°C |
| Cold Start | -40°C |
Features included in programs currently in orbit, such as ICO and Terrestar, and also delivered.
