GPS positioning faster than 1Hz


I am a systems engineer working with various instrumentation devices for ground platforms. These platforms can vary in speed from 0-60+mph. Current instrumentation provides TSPI at 1Hz and is based on GPS. We are looking at a new system that claims to provide TSPI up to 20Hz. I have no additional details at this time on what additional sensors are in the loop.


Since GPS uses 1PPS, how do you get 20Hz TSPI? IMUs?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
