1 Purpose and Function
The ADM50 terminal consists of a microcontroller, non-volatile memory, a GLONASS/GPS
module, a GSM / GPRS module, an accelerometer, an alarm button.

— General view of the ADM50
GLONASS/GPS module is for receiving signals from GLONASS/GPS satellites and
determining the geographical coordinates of the location (latitude, longitude and altitude), as well
as the exact time (GMT), speed and moving direction.
The GSM/GPRS module establishes and supports outgoing TCP/IP connection, periodically
transmitting information packets to a dedicated server with a static IP address or domain name,
and also receives and sends SMS messages by means of GPRS packet data transmission
technology.
The accelerometer is used to determine the level of vibration, which manages switching of
energy-saving functions in the automatic mode.
The "SOS" alarm button is used to activate a mechanism for sending an SMS message and
sending an information packet with the alarm flag to the server.
After switching-on the tracker receives information from the satellites of the GLONASS/GPS
system, determines its location, speed, time and establishes a connection to the server. After
establishing the connection, tracker transmits the accumulated data with given frequency to the
dedicated server, from which it can be received via the Internet for further analysis and
processing with use of corresponding software on personal computers and other supported
computing devices.
In case of absence of communication with the server, the tracker writes information packets
to non-volatile memory, and upon the appearance of the connection, transmits them.
Depending on the selected mode of operation, it is possible to perform the functions of a car
tracker, a personal tracker, or a beacon (bookmark). Tracker can be used to track the location of
any mobile or stationary object - vehicle, cargo, person, animal, etc.
