Abstract:

Two identical Meteor Burst Radio Terminals were developed, fabricated and delivered to the Air Force. Each is controlled by a PC computer in a memo driven manner. Mode of operation is full duplex. The RF frequency range is 40 to 60 MHz with tunning increments of 25 KHz. Data rates are 4, 8, 16, 32, 64, 128, 256, and 512 kbps. Modulation is coherent Binary Phase Shift Keying BPSK and incoherent Differential Phase Shift Keying DPSK. Protocol includes Automatic Repeat Request ARQ with source and destination addressing, message number, start of message and end of message. Messages are packetized and Read Solomon R-S coding is an option. The ARQ is under control of a Cyclic Redundancy Check Code CRCC which detects binary errors within each packet. The terminal is intended to increase meteor trail availability and data throughput by several orders of magnitude - by operating with new antennas that provide much higher gains without sacrificing meteor trail acquisition performance.
