Greetings. This question was asked previously in this newsgroup two
years ago but the answer appears to have been somewhat equivicol.
Has anyone here experience with the Garmin PVT protocol command? I've
written much code to interface to my Garmin handheld receiver and it
all works great except for the PVT command. I though that I needed a
"fix" before it would work, but even with a "fix" the device does not
deliver PVT packets--- it just sends an ACK stating it received the
startpvt command correctly.
My question is, do some Garmin models not support PVT? Why would a
device, that has a 3D fix, not send PVT packets when asked to?
Thank you for your time and attention. :-) Some days I really hate
computers, though GPS receivers are still cool.
There are no units that I know of that do not send PVT. PVT is one of the hardest of the protocols to implement. I have no idea why Garmin chose to implement it that the way they did. I would much rather have seen it work just like all of the other protocols.
You might want to check out my class library and ActiveX control for the Garmin. I have PVT working fairly well. I also have a new version in Beta, and I have made vast improvements in handling PVT. If interested please go to www.stempsoft.com. If interested in the Beta test, please contact me at the email address found on the website.
