The PPS can be good (pi kernel support is stable), but one needs to be careful as some modules PPS signal has a great deal of instability.
Some U-Blox modules support the additional ground based navigation signal and cellular beacons. This is recommended in addition to the 3 satellite networks classes, but note some modules will not work with some antennas (get the unified hardware with built in antenna/lna if unsure about RF notes).
Best regards, =)
- hcfman 3y agoIf you have good sky visibility, then I don't need an antenna. Though this often tends to mean putting a Pi outside. I'm also using just the first Antenna I find actually.
