Re: [Orekit Users] question on using Orekit

[paulcefo <paulcefo@buffalo.edu>]

Hello Alfred,

Could you describe in a little more detail the content and format and 
time distribution of the on-board navigation data from the GPS receiver?

Also the approximate orbit of the satellite carrying the GPS receiver?

Also the accuracy requirements on the determined orbit? And is there a 
prediction accuracy requirement?

An does the satellite stationkeep?

As an aside, I am drinking coffee from my Radarsat (Radarsat 1) mug as I 
write this.

regards,

Paul Cefola
