Med size SAM GPS - MRO10038 
The mRo SAM GPS V2.0 is based on the old and now retired mRo mini SAM. The main difference is that it uses an ideal ground plane of 40mm x 40mm as recommended by uBlox. This makes it a little heavier at 10.3 grams versus 7.6 grams, but it also gives you an increase from ~22 dB-Hz to ~34dB-Hz, which is a lot of gain for just 2.7 grams! We saved some weight with a new generation, smaller rechargeable coin battery and a thinner PCB.
Compared to the IST, the IST8308 has less temperature drift, more sensitivity, and a built-in noise filter. Older GPS versions used the LIS3MDL, which doesn’t even come close to the performance of the old IST8310, let alone the IST8308.
mRo SAM GPS + IST8308 Mag (Med Size) Supports: Ardupilot and PX4.
