In a ESA commissioned activity named GNSSW-LEON4, it was implement an on-board Software Defined Radio GNSS (SDR-GNSS) receiver on a GR-740 on-board computer using RTEMS 5 with SMP.
At a first phase an optimized SDR-GNSS was ported to RTEMS 5 with SMP using the 4 cores of the GR740 and on a second phase it was ported to a TSP paradigm using AIR hypervisor.
The porting an already optimized GNSS- SDR application into SMP and later into the TSP paradigm with also SMP at same time brought several challenges, specially too ensure the execution of all tracking software within a temporal deadline.
