4.1.3.11 Init Receiver 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 the GNSS receiver 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.

4.1.3.12 Init Receiver 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 submenu enables the user to change the receiver’s system time for
initialisation. 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 system with any time. Note that the NTP will
not synchronize to GNSS 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.
