International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / Generally, to meet the Telemetry and Tracking functions in space probes, RF packages are
realised using dedicated circuit configurations and different building blocks. While this
approach is warranted for certain Space missions, for some Space programmes, which are
basically Technology demonstrators and where the main emphasis is on higher flexibility
with minimal complexity - usage of multifunction RF modules (MFRM), would be highly
avantageous.
The MFRM, which can be considered as a RF package, has a flexible configuration and is
built around Common basic building blocks like broadband MMIC, wide band amplifiers,
switches, Dielectric Resonant Oscillators (DRO), Numerically Controlled Oscillators
(NCO), etc. It also has a Microcontroller, whose function is to select the required
configuration and make necessary interconnections between the building blocks, so as to
achieve a specific end function, based on the pre set commands from system designer. The
commands can either be preprogrammed or they can be through uplink Telecommand
signals from the ground stations.
A brief outline of the results of the proto unit of a MFRM which can be configured for
different end RF functions, through a microcontroller is presented in the paper.
It is expected that in Space missions like LEO programmes, Microsats, Reentry,
Microgravity experiments etc, the MFRM approach would offer greater flexibility to the
system designer at reduced-cost, complexity and production turn around time.
