New lightweight and low(ish) cost differential GPS units are being investigated to measure ice flow. They must find a solution fairly quickly after being powered-up (base and rover), which is expected to be roughly +-2cm accuracy. These are the units under test:

  • Ublox M8P
    • using the application board C94-M8P
    • can use GLONASS but only uses L1
  • Swift Navigation Piksi Multi
    • which is an L1/L2 receiver
