Teltonika 1202

Rating : 3/5

Our Verdict

This device is fair in performance, good product for the price they offer.


Internal GPS/GSM Antenna makes easy installation


16 MB Internal memory is good for offline storage

Cheap compared to other devices


Power circuitry is not good, gets short easily

Internal battery is of poor quality and not much capacity

Inbuilt GPS Antenna is error-prone and gives poor location in the city

GSM module is not documented and performance is fair. It however loses signals easily.


Teltonika FM 1202 does almost everything that you usually want a GPS tracking system to do, that too at a reasonable cost. Internal GPS & GSM antennas make it easy for those who wish to covertly track their drivers without their knowledge.

FM 1202, an upgraded version of FM 1200 is blended pretty well for GPS tracking applications that fetch continuous data for real time location updates (even for a 5 sec update interval). With additional inputs & outputs, FM 1202 model makes it easy enough to monitor and control external devices, say for e.g., temperature sensors used in reefers of FMCG carriers. This device has a USB port for device status log output & entering configuration. Teltonika FM 1202 is one of the rarest of its kind with a digital input exclusively reserved for ignition status to nullify the negative impact (showing un-occurred idling events) caused by certain GPS devices in the past.

Waterproof GPS tracking device

Ever heard of a GPS tracking device with waterproof housing? Yea, you heard it quite right, Teltonika’s FM 1202 is tested and proved IP67 (Ingress protection), which indicates this is a total dust-proof & waterproof device that can survive an immersion level of up to 1m, that’s not bad for a GPS tracking device fitted inside vehicles that usually run through the roads, yeah?

Internal Circuit of Teltonika 1202

Internal Diagram of FM-1200

An integrated flash memory

An integrated flash memory of 16MB lets you store up to 100,000 records in case of your vehicle’s battery failure, that means even with continuous location updates every minute, FM 1202 can save your location data internally for up to 10 days which makes it a huge bargain at a reasonable cost. Not just that, this GPS tracking device has a built-in battery that works for an extended period of time, if someone disconnects it from the vehicle’s power source. Enhanced with a deep sleep mode and advanced motion sensors, this Teltonika device keeps an eye on vehicle movement and ignition input, thereby waking up the device and making it active that was in low power consumption mode while the vehicle was stopped/resting.



The ARM® Cortex®-M3 processor is the industry-leading 32-bit processor for highly deterministic real-time applications, specifically developed to enable partners to develop high-performance low-cost platforms for a broad range of devices including microcontrollers, automotive body systems, industrial control systems and wireless networking and sensors. The processor delivers outstanding computational performance and exceptional system response to events while meeting the challenges of low dynamic and static power constraints. The processor is highly configurable enabling a wide range of implementations from those requiring memory protection and powerful trace technology to cost sensitive devices requiring minimal area.

Teltonika TM11Q (GSM Module)

TM11Q is internal model of Teltonika and doesn’t have any detailed information about the same. We tried to contact Teltonika for the documentation but no response was received from their side. We guess this is a generic model almost equivalent to SIM900 which is made by Simcom

Technical Information about internal battery

Ni-MH rechargeable battery, 7.2V, 400 mA.

FM1202 operating time with internal battery depends on temperature, data sending

frequency (SMS and GPRS), and accumulator age, number of charge/discharge cycles

GPS (U-Blox NEO 6M)


  • U-Blox NEO-6M onboard, with high-gain active antenna
  • TTL level, compatible with 3.3V/5V systems
  • Default baud rate 9600, configurable via u-center
  • IPX interface, for connecting different active antennas
  • Chargeable backup battery, keeps the ephemeris data when power down, supports hot starts
  • Onboard EEPROM for storing configuration information

The NEO-6 module series brings the high performance of the u-blox6 position engine to the miniature NEO form factor. NEO 6 has been designed with low power consumption and low costs in mind. Intelligent power management is a breakthrough for low-power applications. These receivers combine a high level of integration capability with flexible connectivity options in a small package. This makes them perfectly suited for mass-market end products with strict size and cost requirements. The DDC interface provides connectivity and enables synergies with U-Blox LEON and LISA wireless modules.

GPS Antenna

u-blox NEO-6M is best in the class but the antenna used in the device is not so good. The antenna will not provide the accurate path when there is a little bit interference presence in the atmosphere and also it doesn’t capture the signal under any roof and must be placed under the sky.
