GoPro GPS not working? - Performance stickers and telemetry FAQ
[ Edited ]

My GoPro video shows no GPS path (performance stickers). Why?
GPS is only recorded in your videos if you get a GPS signal BEFORE hitting record. You know you have a signal when the GPS icon (a map pin) is white. You will usually only get a reliable signal when the camera is outdoors with an unobstructed view of a clear sky. The GPS antenna is next to the record button, so don't mount the camera upside down, if you can.


I had a signal before hitting record, but I still don't have GPS gauges. Why?
On GoPro's Quik video editor, gauges only show up if the GPS signal is good. GoPros rely only on satellites to get a location (as opposed to mobile phones, which use cellular antennas too), so any obstacle around you might hinder the GPS signal and prevent Quik from showing the telemetry overlays. The location of your camera plays a big role too. Over your helmet is better than under your chin, outside the car is better than inside it, and so on. Also, the longer you wait to hit record, even after the GPS icon is on, the better the signal will be, usually.


How can I check that my GPS data was recorded if Quik does not recognize it?
You can see all the telemetry your camera records with the Telemetry Extractor.

 

Is there no way to activate gauges / performance stickers in Quik for videos that contain GPS data?
Yes. You can use the GoPro GPS Quick Fix.

 

How do I know if a location and time are good for recording a GPS signal?
You can use popular drone apps like UAV Forecast (available in the Apple app store and Google Play) to get an estimate of the number of satellite locks you are likely to get at any location and time of day. An estimate of nine satellite locks or better will give the best results. Unseen environmental factors can interfere with the camera's ability to capture GPS. Examples include Solar Weather (Kp Index), multipath propagation, radio wave interference, and high level cloud cover.


Should I use the QuickCapture feature (power on and record automatically)?
No. The camera needs time to acquire satellite lock before the recording begins. If the camera does not have at least four satellites locked and giving good location data before recording begins, GPS data will not be captured. Even if the camera does acquire adequate satellite data during the recording, if it does not do so BEFORE the recording begins, it will not be captured.


My camera always gets bad signal, even in wide open spaces
Some models appear to be more reliable than others (for example, Fusion seems to get very accurate locations whereas Hero 7 can be hit and miss). Some specific units also seem to produce better results than others. If you suspect that your camera GPS might be faulty contact the GoPro Support Team.


Quik mobile (Android/iOS) shows gauges but Quik desktop (Windows/macOS) doesn't!
To reduce the amount of inaccurate readings (Such as GPS reporting faster or slower speeds than was actually occurring), GoPro increased the threshold for good data in their mobile app. They have reported that they are actively working on fine tuning this to reach the best, and most usable data. Also, the quality threshold that Quik requires from the GPS signal might vary between platforms. Recently, we also found out that some new cameras (Hero8, Max) are still not fully supported in Quik desktop. A fix is expected. In the meantime, you can use the GoPro GPS Quick Fix.

 

Which cameras contain telemetry?
All cameras since the Hero 5 contain telemetry.
Hero 5 Session, Hero 2018 (to be confirmed) and Hero 7 White contain basic data (gyroscope, accelerometer).
Hero 5 Black, Hero 6 Black, Fusion, Hero 7 Silver, Hero 7 Black, Hero 8 Black and Max also contain GPS. The newer the camera, the more metadata streams (sensors) it contains.
The Hero 4 Black can theoretically record metadata into the videos if attached to a Bluetooth metadata device. All the other mentioned cameras should be able to take in external Bluetooth telemetry too.

 

What other data streams exist?
New cameras include multiple streams, such as: Exposure time, White balance (Kelvin and RGB), Sensor ISO, Average luminance, Image uniformity, Scene classification, Face coordinates and details (smiles), Predominant hue, Camera orientation, Image orientation, Gravity vector, Wind processing, Microphone is wet, AGC Audio level, Disparity matrix... In most cases tools to use these data easily do not exist yet.

 

Do edited or processed videos have metadata?
Generally, no. Some of the GoPro processing software (Fusion Studio) does retain some of the metadata, but it's not something you can rely on.

 

My performance stickers are showing mph but I need km/h (or vice-versa)

On Android or iOS, try changing the language or regional settings of your phone to a country/language where the desired units (metric or imperial) apply. On Windows or macOS, the settings tab of Quik lets you change units.

 

I want to use the metadata in different ways
Here's a list of resources that will allow you to use the data in other apps (After Effects, Virb Edit, Google Earth...), do racing related stuff with them, or even code your own custom software: GoPro telemetry resources.

 

I need inspiration. What have people done with telemetry so far?
Here's a playlist with some examples, but there are many more things you can come up with! GoPro telemetry, metadata and sensors.

 

I have more questions

Very helpful would be, that the App gives an alert or hint, when the GPS does not work properly.

We use the Gopro for business reasons. The camera is fixed outside of a car and we capture infrastructure data.

The movies will be linked inside a GIS-application. Important is, that the GPS-path can be related to the GIS-mapping data.

 

Strange enough: I used the GOPRO TELEMETRY EXTRACTOR - AND the GPS-data are collected --- but not showed up in Quik.

The only remedy is, to export this data into After effects and use it as a layer on top of the movie............

@rolandc4675 Ye, it would be useful to have the app inform you about the quality of the GPS data, and even let you decide whether you want to use it or not... despite the quality.

 

Would your company be interested in a feature in the Telemetry Extractor that exported every frame of a video with EXIF location data in it?

Is this function already available?

made another test today with two movies: one is fine with correct path, the other shows only a part of the route-section....

had never before such instable results. made several hundert movies before, all fine with quite fine GPS.

could this be with the last upgrade for the camera?

@rolandc4675 No. That feature is something I could create if there was enough interest in it.

 

Regarding the data quality, you can check what happens if you load the data in the Telemetry Extractor and set GPS Precision to 10000 and GPS Fix to "Any". You will then see how bad is the data that got filtered out. I don't think this is related to firmware updates, but I can't be sure.
