Term Definition
Performing a FIX Means the GPS receiver is able to compute a
position
Dead reckoning GPS Feature that allows navigation with poor/no
satellites view by the aid of external sensors that
provide course (odometer) and heading
(gyroscope).
Single Coax WAVECOM concept that allows the user to use
only one single coaxial cable for both GSM and
GPS RF signal to connect the WISMO Quik Q2501
module to the antennas.
The antennas are most of the time physically
distinct but connected to the WISMO Quik Q2501
module by a single coaxial cable through an
antenna switch system, saving a second coaxial
cable.
Cold Start Powering up a unit after it has been turned off for
an extended period of time and no longer contains
current ephemeris data. In Cold Start Scenario, the
receiver has no knowledge on last position,
approximate time or satellite constellation. The
receiver starts to search for signals blindly. This is
normal behavior, if no backup battery is connected.
Cold Start time is the longest startup time for GPS
receivers and can be several minutes.
