GPS Rec. error
Codes
Definition Suggested Action
RCVR Hardware
Error: 0010
RF Failure: This
means the receiver is
not sensing a proper
RF signal from the
satellites/antenna.
It could be one of the following, in the order of prob-
ability:
1. Coax open or shorted. Confirm the 5 volts at the
antenna end.
2. Bad antenna. Substitute the antenna, or inject a
signal at the coax.
3. Bad Receiver Module in GPS. Substitute the GPS
unit, or inject a signal at the input.
RCVR Hardware
Error: 0080
ASIC Failure: The
GPS Correlator
ASIC failed self-test.
It could be one of the following, in the order of prob-
ability:
1. The flex cable between the Receiver Board and
Main Board may have come out of the socket in the
GPS.
2. Bad ASIC on the Receiver Module in the GPS.
Substitute the GPS unit.
RCVR Hardware
Error: 0100
BBP Timeout: The 1
mS baseband pro-
cessing timer failed
self-test.
It could be one of the following, in the order of prob-
ability:
1. The 5 volt supply to the antenna could be shorted
out in the coax. This disables the oscillator in the
GPS.
2. The flex cable between the Receiver Board and
Main Board may have come out of the socket in the
GPS.
3. Bad TCXO or ASIC on the Receiver Module in the
GPS. Substitute the GPS unit.
RCVR Hardware
Error: 0400
RS-232 Receive
Failure: The GPS
Receiver did not re-
ceive any initializa-
tion data from the
host computer on the
RS-232 port.
It could be one of the following, in the order of prob-
ability:
1. The flex cable between the Receiver Board and
the Main Board may have come out of the socket in
the GPS.
2. Bad 32kHz crystal, UART, or processor on the Re-
ceiver Module in the GPS. Substitute the GPS unit.
RCVR Hardware
Error: 0800
EEPROM Failure:
The EEPROM failed
sum-check self-test
Bad EEPROM. Return for service.
