Hey all. I'm unsure how to calculate the pseudorange using the measurement output from the AllStar receiver. Has anyone tried this with an AllStar receiver before?

I'm assuming that "predicted GPS time" is the estimated time of receipt. So I'm just having trouble finding the transmission time. The code phase measurement is available, however I don't know how to find the transmission time of the leading edge of the first chip.

Any help would be greatly appreciated. The AllStar documention is really frustrating me - you can find it at [I can't post links yet. First result on google for 'AllStar User's Manual' should do the trick] - see page 81 (as per Acrobat Reader) for the measurement block data message.

Thanks.

Nick.
