GLOBAL POSITIONING SYSTEM (GPS)
DESCRIPTION AND OPERATION
1. GENERAL (Figure 1)
The GPS is a system of radio-navigation by satellites which allows to solve the problem of an aircraft location anywhere (tridimensional positioning : latitude, longitude, altitude).
The optional system consists of :
- an A78 GPS receiver,
- an E48 GPS antenna,
- an E023 relay box,
- a J89 "data loader" jack,
- a removable database cartridge (mounted at the back of the GPS receiver).
The GPS also uses components of M6 advisory panel - refer to 31-50-01 :
- the switch / annunciator "NAV 1 - GPS",
- the annunciator "WPT / WRN",
- the annunciator "MSG", The GPS also uses the "RADIO MASTER" switch.
The GPS gets altitude coding information from the encoding altimeter - refer to 34-11-00,
The GPS sends :
- an altitude - alert audio signal to the audio control box - refer to 23-11-00,
- guidance information to the optional autopilot system - refer to 22-12-00.
The GPS also uses :
- an interface kit used to load the database from a personal computer via the data loader jack,
- the blower of the radio air cooling system.
VHF transmissions may affect GPS signal reception. Filters are inserted in line with each VHF transmission line.
Using the switch / annunciator "NAV 1 - GPS" of M6 advisory panel, the remote relay box E023 provides switching of NAV 1 or GPS information to the horizontal situation indicator of the heading reference system -refer to 34-21-00.
The GPS system is electrically supplied by "BUS 3" bar via the "GPS" circuit breaker.
