OOO Neomatica. Terminal ADM007 GLONASS / GPS. Rev.1.3 dated 13.09.2019

The tracker with the GLONASS/GPS module ensures time and navigation parameters
measuring based on GLONASS and/or GPS satellites. After being connected to the power supply,
the tracker starts receiving data from satellites, locating itself, identifying speed, time, measuring
voltage in inputs and connecting to the server. After being connected to the server, the tracker
transmits thereto the data packets with the pre-set frequency or when an event occurs. If for any
reason the connection to the server fails, all the information will be saved in the tracker
non-volatile
memory and transmitted as soon as the connection is restored. If there is no signal from GLONASS
and/or GPS satellites and there is GPRS connection the time is synchronized via NTP protocol with
one of the available public servers. The points will be recorded without data about location.
Data transmitted by the tracker:
⎯
GMT date and time;
⎯
coordinates (latitude, longitude, altitude);
⎯
speed, acceleration and travel direction;
⎯
number of satellites when fixing a navigation problem;
⎯
precision loss factor in a horizontal plane;
⎯
voltage values on analogue input;
⎯
data about events occurred;
⎯
device status
