We have discovered that the GPS correction data for the StarFire navigation system is now free.

Therefore, we happy few here at BotHeads are investigating hacking its broadcaster (INMARSAT) to add differential GPS to the BuckyBot.

Maybe we’ll have it done by next St. Crispin’s day.

Will welcome any help.  Frequency is around 1.53 GHz.

Will a GPS antenna/receiver with a new SAW filter work, ya think?

Does anybody know where I can get a SAW for 1.53 GHz? GPS SAW’s haven’t the bandwidth to get up there…
