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,
- a K109 relay,
- 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 "GPS CRS OBS - GPS CRS LEG",
- the switch / annunciator "GPS APR ARM - GPS APR ACTV",
- the annunciator "MSG - WPT",
- the K1 relay.
The GPS gets :
- altitude coding information from the encoding altimeter - refer to 34-11-00,
- data from the optional SHADIN fuel flow system - refer to 73-30-00,
- data from the symbol generator of the EFIS system - refer to 34-28-00. The GPS sends :
- an altitude - alert audio signal to the audio control box - refer to 23-11-00,
- data to the symbol generator of the EFIS system - refer to 34-28-00. The GPS also uses :
