the lora/GPS hat is based on the s* 1276/s* 1278 transceiver. the add on l80 GPS (base on mtk mt3339) is designed for applications that use a GPS connected via the serial ports to the raspberry pi such as timing applications or general applications that require GPS information.the transceivers of the lora/GPS hat feature the lora long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption. the lora/gpd hat can achieve a sensitivity of over -148dbm using a low cost crystal and bill of materials. the high sensitivity combined with the integrated +20 dbm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. with alwayslocate technology, the lora/GPS hat can adaptively adjust the on/off time to achieve balance between positioning accuracy and power consumption according to the environmental and motion conditions. the GPS also supports automatic antenna switching function. it can achieve the switching between internal patch antenna and external active antenna.moreover, it keeps positioning during the switching process.
