I've been examining the GPS recordings of walks made on my iPhone. The GPX files should of course contain one text line for each position recorded, containing position, altitude and a timestamp. But occasionally (less than 1%) the timestamp is obviously missing. The 4th line of this small extract shows an example: trkpt...

I have written a track editor that runs on Android tablets, and it is now available for beta test on the Google Play app store at: https://play.google.com/apps/testing/com.lewlasher.trackEditor GPX Track Editor is similar in functionality, as a first approximation, to other track editors such as GPS TrackMaker, which I have been using for years on the Windows platform, primarily to make maps of...

Seems fairly quiet here but I'm hoping that one of the resident experts can help me get to the bottom of some odd behaviour please.

We've just got a dashboard camera for the car, and it also has a GPS receiver. I was looking at the tracks of my wife's journey to work. At one point she passes under a long bridge beneath many OHLE-electrified (*) railway tracks close to a station. The GPS track seems to go haywire, showing her going roughly opposite to the real direction, and this begins just *before* she goes under the...

An article in the July 2016 GPS World magazine states that raw GPS measurements will be available to apps in the Android N operating system, which will be released later this year. This means you can get pseudoranges, doppplers, and carrier phase from a phone or tablet!

Testing quantised inertia on the emdrive http://arxiv.org/abs/1604.03449v1 It has been shown that truncated cone-shaped cavities with microwaves resonating within them move slightly towards their narrow ends (the emdrive). Standard physics has no explanation for this and an error has not yet been found. It is shown here that this effect can be predicted by assuming that the inertial...

Has anyone else been having problems downloading offline maps in the Here Maps app on Android? In the past it's been a fairly painless process, but when I tried it the other day (I had to remove and reinstall the app after it stopped giving me turn-by-turn directions to some postcodes, even though it worked out a route), I found that it was very reluctant to download maps. Often it would...
