Receiver design for a pseudo noise coded radio beacon transmission
Abstract
A test transmitter and a microprocessor-controlled receiver system are described, the transmitter consisting of two independent crystal controlled frequency sources at 360 and 40 MHz. A specification is proposed for a geostationary satellite transmission. The proposed parameters include frequencies of 140 and 360 MHz, power of 1 W effective isotropic radiated power at each frequency, and linear polarization. It is noted that if the pseudo noise modulation concept were applied to a low orbit satellite beacon, then a shorter code length would be desirable to reduce the code acquisition time.
