## Description

The GP-1818MK is a low-cost - high performance GPS module with built in antenna. It can provide position, velocity, and accurate timing through the standard NMEA-0183 protocol. Being low power and compact in design, the GP-1818MK is perfect for basic tracking and positioning, especially with respect to battery powered systems.

This is the recommended replacement for those using the [20U7 Module](https://core-electronics.com.au/search/?q=13740). There should be minimal changes needed to move from that module to the GP-1818MK. The module comes terminated with a 3-pin connector similar to that on the [20U7 Module](https://core-electronics.com.au/search/?q=13740). It features the same 56-channel, low power capabilities as well.

- Build on high performance GPS single chip MT3337
- High Sensitivity -165 dBm
- Low power consumption: Max 55mA @ 3.3V
- Integrated LNA with low-gain mode for active antenna option
- 66 channels in Search mode and 33 channels "All-in-View" tracking
- Up to 60,000 simultaneous search windows for fast TTFF and high sensitivity acquisitions
- Average cold start time under 29seconds (open sky)
- Support standard NMEA-0183 protocol
- Patch Antenna Size: 18mm W X 18mm D X 7mm H
- RoHS compliant (Lead-free)
