How much do GPS receivers affect the local GPS signal strength? While a receiver doesn't reduce the signal strength much, it would seem that it has to have some effect. Perhaps the effect was insignificant with only 1E6 receivers, but, with GPS in many mobile phone there may now be 1E9 receivers, 1000 times as many. Perhaps in the future when every packaged item for sale has a GPS receiver in...

Hi, I'm looking at Glonass and I'm a bit confused on the slot number assignment and the associated frequency channels and NMEA ID. Glonass slots are numbered 1-8 in plan 1, 9-16 in plane 2 and 17-24 in plane 3. For example, if I'm not wrong, NMEA outputs glonass satellites by their slot(+64). GPS instead outputs the PRN. Basically with the GPS any satellite can have a PRN (and so, an ID in the...

How do I update my Evesham Nav-Cam 7700 Sat Nav

Hi guys, I have just purchased a new TomTom XL2 IQ routes fitted with the fairly new style 'easyport' circular mount. The mount was already fitted to the sat nav device in the box. I am sure this must be quite apparant to most people, but i can't for the life of me work out how to remove the mount from my TomTom sat nav device. There are no instructions on how to do this with the device. The only...
