General Description
The Gotop GT-1613-MTGN is a complete
GPS&GLONASS engine module that features
super sensitivity, ultra low power and small form
factor. The GPS&GLONASS signal is applied to
the antenna input of module, and a complete
serial data message with position, velocity and
time information is presented at the serial
interface with NMEA protocol or custom
protocol.
Its –165dBm tracking sensitivity extends
positioning coverage into place like urban
canyons and dense foliage environment where
the GPS&GLONASS was not possible before.
The
small
form
consumption make the module easy to integrate
into portable device like PNDs, mobile phones,
cameras and vehicle navigation systems.
Applications
 LBS (Location Based Service)
 PND (Portable Navigation Device)
 Vehicle navigation system
 Mobile phone

  • Page 8: Power Supply

    Power supply solutions for GT-1613-MTGN module are listed as the following.  The simplest power circuit for GT-1613-MTGN module is 3.3V power source connected to VCC pin and VBAT pin of the module directly. In this case, once you powered on the module, the full cold start will be implemented.
  • Page 9 GPS&GLONASS Receiver Module Figure 4: Reference Circuit for Power Supply If your power supply circuit adopts the design mentioned above , GT-1613-MTGN module does not support EASY technology and backup mode as well as other modes related to it,e.g. AlwaysLocate ™...
  • Page 10: Operating Modes

    GT-1613-MTGN GPS&GLONASS Receiver Module VCC does not supply power for RTC domain in GT-1613-MTGN module, so the VBAT pin must be powered externally. Furthermore, it is strongly recommended to supply power to VBAT through a backup battery, which can ensure GT-1613-MTGN module supports EASY technology and improves TTFF after next restart. For details about TTFF, please refer to chapter 1.2.
  • Page 11: Standby Mode

    Backup mode consumes lower power than standby mode. In this mode, only the backup supply VBAT is powered on while the main supply VCC is switched off by host or the TIMER signal of GT-1613-MTGN. In order to enter into backup mode autonomously via the TIMER pin, an external switch circuit is necessary.
  • Page 12 When this command is executed successfully, TIMER signal will be pulled down to close the power switch, so GT-1613-MTGN module can go into backup mode as the main power VCC is cut off. For this case, pulling the GPS_EN signal high by host is the only way to wake the module up.

    GPS&GLONASS Receiver Module 2.4.4. Periodic Mode Periodic mode is a power saving mode of GT-1613-MTGN that can control the full on mode and standby/backup mode periodically to reduce power consumption. It contains periodic standby mode and periodic backup mode. The format of the command which enables the module to enter into periodic mode is as follows: ...

    GT-1613-MTGN GPS&GLONASS Receiver Module The following figure has shown the operation of periodic mode. When you send PMTK command, the module will be in the full on mode firstly. After several minutes, the module will enter into the periodic mode and follow the parameters set by you.
  • Page 15: Flp Mode

    FLP function is disabled by default. You can enable FLP by SDK or PMTK command. Sending “$PMTK262,1*29” will enable FLP function, and wait until GT-1613-MTGN module gets a valid fix. Then wait at least 60s for GT-1613-MTGN to enter FLP mode. FLP function will be disabled after sending “$PMTK262,0*28”.
