A system is being designed to use a 30 GHZ link with a 300HZ bandwidth to receive signals from a navigation spacecraft at an altitude of 20,200km, with a maximum slant range of 24,700km.  The satellite transmitter-antenna gain is 25db and the handheld unit receiver gain is 5db.  The transmitter power will be 18W.  If the handheld receiver temperature is 500K, will this be an effective link (S/N at least 10 or 10db)?  If not, what could you change to improve the link?
