With the TTGO (LILYGO) GPS LoRa board you can build a very cheap and accurate LoRaWAN GPS tracker. 
The TTGO T-Beam from LilyGO is a microcontroller based on an ESP32 including a built-in SX1276 LoRa chip and a NEO-M8N GPS module. The CP2104 USB to serial converter makes it easy to program, even as an Arduino. The board has a micro USB connection with which it can be programmed and/or powered (micro USB cable not included) .
