Latest daily products

The orbits and clocks generated in real-time by the ODTS are consolidated on a daily basis in sp3 and clk files, a few minutes after midnight UTC. The latest daily solutions are available here. These files can be particularly useful for users who want to test their PPP software in post-processing. A file (prefix .bias) contains elementary biases to be added to each observable (pseudo-range and phase) to allow direct ambiguity resolution on widelane and narrowlane combinations.
