I search different online PPP (PRECISE POINT POSITIONING) services, but I am new in geodesy, so I can find only a few services like:

  1. CSRS-PPP (Canada)

  2. GPS Analysis and Positioning Software (GAPS)

  3. magicGNSS

Are there any other PPP services?

You may also use APPS (https://pppx.gdgps.net/) It's a technology from NASA's Jet Propulsion Laboratory and they use there own GipsyX/RTGx software for processing the GPS measurements.
