(d) Clock warm-up mode

If thermal stabilization of the RPU internal clock has not been at-

tained by the end of the Initialization mode (acquisition is not yet

possible), the RPU is set to the clock warm-up mode; the position,

speed and the time are maintained by available external aids. Othe-

rwise the RPU switches directly into the next mode (DR or Sky Reac).

(e) Sky Reac Mode

This mode (general sky search) is activated whenever one of the pa-

rameters essential for position-fixing is absent or detected as

false, i.e.:

- The almanacs, whenever they are absent or out of date,
- The time or the position, whenever they are invalid,
- whenever the Position-fixing mode cannot be triggered 20 minutes

after the power has been turned on.

In this mode, the RPU seeks to acquire the missing parameters as

rapidly as possible by conducting a search for visible satellites

(Search Sky).

(f) DR (Dead Reckoning) mode

This mode is engaged if the number of satellites used for navigation

(available ephemerides, satisfactory geometry) is insufficient to

activate the Position-fixing mode.

In this mode, the RPU performs the following functions:

- Dead reckoning navigation according to the best external aids

available (inertial or pressure altitude data: true air speed,

true heading, magnetic heading, altitude, air speed, vertical

speed).

- Acquisition of usable satellites according to criteria of visibi-

lity, geometry, state of health, manual commands...

- Tracking of "locked" satellites

(g) Position-fixing Mode

In this mode, the RPU acquires and pursues a maximum of 8 visible

satellites by using the "GDOP" (Geometric Dilution of Precision)

criteria in such a way as to continuously supply the best position-

fixing solution (GPS sole or assisted position-fixing).

Depending on the number of satellites used for position-fixing, the-

re is unassisted position-fixing (number of satellites

≥

4) and

assisted position-fixing (number of satellites

≤

3).
