I've been mostly lurking, but I have one question.. is it possible to
get position fixes from GLONASS birds as well? I suppose it depends on
the front end filters in the hardware interface. I know I seldom get a
12-satellite lock from just the GPS satellites. Are the two systems
different enough to eat an excessive amount of FPGA space?
