jdlaing Posted November 17, 2013 Share #21 Posted November 17, 2013 Advertisement (gone after registration) GPS is a broadcast system, not a 2-way communication system. Telemetrics require a wireless network connection like GSM, CDMA, LTE, etc. (or a private radio network system such public safety and utilities). GPS Satellites cannot track a GPS receiver. Other things can. Just as soon as it is fired up. Get used to it. It is the new millennium. Link to post Share on other sites More sharing options...
Advertisement Posted November 17, 2013 Posted November 17, 2013 Hi jdlaing, Take a look here Battery Usage: EVF + Multifunction Grip. I'm sure you'll find what you were looking for!
jdlaing Posted November 17, 2013 Share #22 Posted November 17, 2013 GPS DOES NOT work two ways, A GPS unit like the MF grip looks to see GPS satellites, and then knows where it is on earth. The GPS satellites CANNOT track a receiving unit. Do your research. I never said Satellites can track a GPS receiver. Other things can. Just as soon as you turn it on and request a signal from the satellite. Get used to it. It's the new millennium. Link to post Share on other sites More sharing options...
esophoria Posted November 17, 2013 Author Share #23 Posted November 17, 2013 Daryl, The draining took place over a 4.5 hr period. I even turned off the camera off at times. Perhaps, that's not a good strategy-- since when you turn on the camera...the GPS unit needs about 2-5 minutes of hunting to give you a reading...perhaps that is more battery draining then keeping the camera on.

darylgo Posted November 17, 2013 Share #24 Posted November 17, 2013 Esophoria, 4.5 hours could turn into 2 hours in a very cold climate. This makes me wonder if there is some synergistic effect with the gps and evf....are we the beta battery testers? Link to post Share on other sites More sharing options...
esophoria Posted November 17, 2013 Author Share #25 Posted November 17, 2013 Indeed-- we just may be the beta team! Link to post Share on other sites More sharing options...
darylgo Posted November 17, 2013 Share #26 Posted November 17, 2013 Glad to join you and the team, my grip arrives Monday however the M body is in New Jersey for rangefinder adjustment. 14 month wait for the body/grip, well worth it! Link to post Share on other sites More sharing options...
jip Posted November 17, 2013 Share #27 Posted November 17, 2013 Advertisement (gone after registration) I never said Satellites can track a GPS receiver. Other things can. Just as soon as you turn it on and request a signal from the satellite. Get used to it. It's the new millennium. It doesnt REQUEST a signal, the GPS satellites just broadcast even if there would be 0 GPS receivers active. Neither is a receiver traceable.... Since it does NOT broadcast anything. The thing that makes cellphones traceable is because they know where they are (GPS) and then send that data to some services. Like 'find friends' on Apple's iPhone/iPad. Again, state the two opposites a GPS receiver never requests it just looks for what's there. Like a radio when it's just on playing music, it in now way has to 'request' that data from the transmitter. So the Leica M is NOT traceable, since it DOES NOT transmit a single thing...

algrove Posted November 17, 2013 Share #28 Posted November 17, 2013 ....are we the beta battery testers? I have a feeling we are beta testers with about everything with this M240. -lug nuts -WB -colors -MF grips -batteries? What's next? Link to post Share on other sites More sharing options...
Guest borge Posted November 17, 2013 Share #29 Posted November 17, 2013 GPS Satellites cannot track a GPS receiver. Other things can. Just as soon as it is fired up.Get used to it. It is the new millennium. "Other things can." Very good description. Please be specific if you intend to spread FUD in this way. Cell phones can be tracked not because of their GPS functionality but because you can easily triangulate the voice or data traffic sent and received by the phone. This has nothing to do with the GPS in the unit at all. The GPS unit itself cannot be tracked. Link to post Share on other sites More sharing options...
sisoje Posted November 17, 2013 Share #30 Posted November 17, 2013 I have a feeling we are beta testers with about everything with this M240.-lug nuts -WB -colors -MF grips -batteries? What's next? I on the other hand, have no complaints about my M240... Don't need gps, Don't need grip (or thumb up, or thumby or...), Don't use evf except lenses wider than 28 (longer than 90), No lugs issue, No color issue (shoot raw only, and all images go to LR anyways...), No lock ups so far...

Just as soon as you turn it on and request a signal from the satellite. Get used to it. It's the new millennium. Nonsense. GPS coordinates are calculated entirely on the receiving device, which is where they stay unless your device (such as a smartphone) is using some application that sends them somewhere else. Smartphone apps are pretty careless about doing this, of course, but it's the use of the app, not the use of GPS per se, that transmits your location. (Mobile phones also leak your location in other ways, which can be as revealing as a GPS-calculated location, but that's a different technology). For a discussion of the various ways location can be tracked, see, for example, http://www.crypto.com/papers/blaze-20130425_final.pdf Link to post Share on other sites More sharing options...

jaapv Posted November 18, 2013 Share #34 Posted November 18, 2013 Most smart phones have location services activated, half the cars on the road have their satnav running, not to mention boats, airplanes, cyclists and handheld GPS devices. We do know the NSA is paranoid about collecting data and that the technical possibilities are endless, but do you really think that anybody is going to pick out your Leica M in this mass of static? As for battery usage - instead of the mechanical M3 we have a camera that is running a large number of processes, some of them energy-intensive. So it drains the battery faster... TANSTAAFL..
