Here are some answers to frequently asked questions about GPS and location. This applies for Android and iOs devices.
How do you know the location within Loquiz?
We ask for high accuracy location from respective services within device. This is compound information that combines GPS, mobile and wifi information into one and serves it to the app. The only filtering we do within Loquiz is that if location estimated accuracy is worse than 100 meters then we do not allow so activate tasks based on that location.
If your location seems to be incorrect within Loquiz it is adviced to switch from Loquiz to built in map application (Google maps or Apple maps) and see if the location there is the same. If it is then this is the best location information available for all the apps.
I have good internet connection but my location is still unreliable.
Good internet connection does not guarantee high location accuracy.
Loquiz relies on high accuracy location data. Mobile signal and Wifi positioning are usually not accurate enough to activate tasks within Loquiz. Having good internet connection enables fast downloads of satellite position information and helps to speed up the initial lock, but the satellite visibility is still needed to activate locations.
My location blob seems not to follow me or is slow to follow me.
This can happen if GPS signal quality is weak and therefore accuracy is low. To understand the accuracy observe the blue circle around your location blob. The bigger the blue area the lower the location accuracy. If the accuracy is worse than 100 meters then no tasks will be activated.
To fix it you need to make sure there is good satellite reception. If you are indoors, move outdoors, if you are close to tall buildings or on narrow street, move to wider street or open place. If you are in deep forest move to open places.
When building games avoid placing tasks into tight locations. If you absolutely need to do it, make the task radius larger. It will not guarantee the activation but might make it easier.
The blob is following me, but is off by some meters.
This might happen when yo are moving on a narrow street and the blob shows you on the side of the street (on top of the building for example). This situation happens because on a narrow street all the satellites the device sees are in lined up. So it estimates signal accuracy as high, but the location is actually slightly off. Specifically the location is good in one direction (along the street), but might be off in another direction (perpendicular to the street).
What to do?
Avoid setting locations onto narrow streets with tall buildings.
If you need to do that make sure the radius is sufficiently big (20 or more meters).
Be warned that if the signal quality is low the location might not activate at all.
I am within a radius of a location, but the location does not activate.
This can happen indoors or close to tall buildings.
Task will not be activated if location accuracy is lower than 100 meters. To understand the accuracy zoom out and check out the blue circle around the location blob. The bigger it is the worse the location accuracy. Even if you are within the location radius but your location accuracy is weak, location will not be activated.
To improve it do not place tasks activated by location indoors and close to tall buildings.
I have two devices side by side, and their location is different by several meters.
It can happen that two devices side by side show slightly different location. This is due to several factors like positioning of the devices, but also past locations. It can be especially visible if the signal quality is not the best or accuracy is ok, but player is close to tall buildings.
It is normal, and unless it affects your gameplay it is nothing to worry about. If the anomaly is large (10 meters or more) then you should check if the location is suitable for the task.
Yesterday the location activated fine, but today I can not get it to open.
GPS satellites positions change in time relative to earth (Galileo is different as it uses geostationary satellites). Depending on the time of the day, the satellite positions are different so if a location is ok for GPS one day then it might be more challenging the next day. For example close to tall buildings the satellites might be blocked by the buildings on one day, but another day more satellites might be visible because of their changed locations.
In open places the effect is not noticed, but within city streets it can be a factor day to day.
Why don’t you improve the location within your app?
Loquiz gets the location directly from the system. Improvements to location quality the device reports are done by improving the satellite infrastructure (new systems, like Galileo), better hardware (satellite chips within phone) and better algorithms within devices operating system. We do very little filtering very cautiously to ensure we do not decrease the location quality.
