NRCAN / csrs-ppp will do L1 only data. Typical results have errror ellipses in the 300-500 mm range. It also seems to be the only free site that handles RINEX V3.xx data. They only use GPS and GLONASS measurements, -------------- >I do not know of any free sites that will post process “L1 only” data. Without post processing, you will not get mm level results.

No... NRCAN is one of the few that do not require both L1 and L2 observables. It also accepts only L1. /Björn Sent from my iPhone > On 23 Nov 2019, at 08:22, Poul-Henning Kamp <phk@phk.freebsd.dk> wrote: > > -------- > In message <SN1PR07MB390174DFEF62F4BF054C814ACE480@SN1PR07MB3901.namprd07.prod.outlook.com>, Mark Sims writes: > >> NRCAN / csrs-ppp will do L1 only data.
