Navigation along a track : what/ where is the off track data I'm being told about?

Hi folks... I'm a long time occasional user who loves Locus Pro (Android) but has never really got Navigation working satisfactorily... particularly when trying to navigate along a path I have created or imported. I set the GPS to high accuracy and the navigation to keep me as close as possible to the path, with frequent warnings if I divert... and I've now had the same issue with 3 phones, with GPS working well in all other apps. Still I find myself perplexed by the voice seemingly telling me I'm way off path... even when the live map shows me bang on it... and even though I know I'm in exactly the same spot. I am frequently told... 'track lies x metres at x o'clock'.. and it may be some wild figure like 80 metres or more. I don't understand it. Where can I see on screen these x metres that I am off track? I would love to know what exactly is meant by the warning. Is it talking about the next point? The nearest? Where is the data please?

Hi Boris,


you have probably set too short interval for out of track notification (settings > navigation > out of track notification). GPS inaccuracy which is common on mobile phones may trigger the announcement despite you are visibly on the track - plus you have checked the "snap to track" feature (settings > navigation > advanced > snap to route.


The distance Locus announces is to the next trackpoint which can be farther than the track line.

Hi Michal thank you for your reply. What interval would you recommend? I will try the 'snap to track' feature. So you are saying that when it says 'track lies x metres at y o'clock' that 'track' means the *next* track point, ok thank you. What confuses me further is that when I check the distance to the next track point it doesn't seem to tally. I suppose only mobile phone GPS inaccuracy can explain the weird announcements as you say. I suppose I just don't notice with other apps. It's quite disconcerting to be told 'track lies 2M at 12 o'clock' and seconds later to be told 'track lies 200M at 10 o'clock'. It doesn't give me much faith following a track on a proper mountain walk from this urban test. Yeah I know I should get a proper GPS.

I agree with this. The message seems to be random and TOTALLY incorrect. Sometimes it is 100m behind me, sometimes 5m in front, or to the left, etc. No link to reality or the next waypoint in anyway. And I have a top of the line Samsung S10+ - hopefuly a good GPS in that. As you say, it is very disconcerting!

Hi Kerry,

strange, my quite middle-of-the-line Xiaomi Note 4 announces direction and distance of the nearest route point correctly. Go to Locus settings > GPS&sensors > Location filter - activate some stronger filter OR try the Google Services assisted location. Also, your compass needs to be calibrated so that this functions works good (https://docs.locusmap.eu/doku.php?id=manual:faq:how_to_calibrate_compass)

best regards

Michal, Locus team

Boris, I personally have 50 metres set as the alert distance but of course, it's too much for a free terrain mountain walk where each meter matters. Nevertheless despite the mobile GPSs are better and better, they still have have quite a large deviation of location fix - despite they indicate otherwise - compared with some pro GPS unit - therefore, I would not rely on an ordinary mobile phone during a free mountain terrain climbing activity.


As for the notification of the next trackpoint - we know it's a problem and we'll try to improve it.


The "snap to track" puts the arrow on the navigation line despite your real location is a bit out of the route - it works in cars and bikes on roads but can be dangerous when in a free terrain.
