Init GPS Position

When the receiver is primarily installed at a new location far away from the last

position saved in the receiver’s memory the satellites in view and their Doppler will

differ so much from those expected due to the wrong position that GPS has to scan

for satellites in Warm Boot mode. Making the new approximately known position

available to the receiver can avoid Warm Boot and speed up installation.

Init GPS Time

If the receiver’s on-board real time clock keeps a wrong time the receiver is unable

to compute the satellites´ correct elevation angles and Doppler. This sub menu

enables the user to change the receiver’s system time for initialization. After the

receiver has locked, its real time clock will be adjusted using the information from the

satellites.

When the antenna is disconnected it is possible to set the LANTIME with any time.

Note that the NTP will not synchronize to a GPS losing its reception or if the

deviation to the system time is larger than 1024 seconds. In this case the menu

Simulation Mode has to be active. After setting the clock manually the system time

will be set and the NTP will be restarted.
