What does it do?¶
GPS Status & Toolbox is a simple program to show all the GPS và sensor data ofyour phone. It is designed to be simple, yet effective. It helps you lớn see what ishappening while the GPS is trying lớn acquire your locations và can be used as asimple compass, as a leveling tool. It will measure the phone’s speed & acceleration,the brightness or the air pressure (if your phone has the necessary sensors.) Theprogram also supports basic navigation functions that are useful when you are outin the wild. The ứng dụng has four main screens plus it can display a system notificationto show GPS data.

The screen has three main parts: The sky grid (G), the signal strengthbar (V) and the instrument panels.
The sky grid (G) shows the GPS satellites above sầu you as the receiver in thephone detects them. GPS satellites (with IDs 1-32) are represented by disks.GLONASS satellites (with IDs r1-r25) are shown as rectangles, BEIDOU satellites(with IDs c1-c33) are shown as crosses (x) while GALILEO sats (with IDs e1-e35)are displayed as plus (+) signs. The kích cỡ of the symbol depends on the signalstrength received from that satellite. The color shows what data is availablefor that satellite và how it is currently used by the phone.
green: satellite is used while determining the locationyellow: all orbital data is available, but the satellite is not usedblue: only rough orbital data (almanach) is availablegrey: orbital data is not available
Usually at least 4 satellites are required to lớn have sầu a lochồng. The more satellites are availablethe more accurate the position will be (khổng lồ a certain limit. i.e. having đôi mươi sats in a loông xã doesnot really increase the accuracy compared khổng lồ 10). Certain phones may opt to lớn use only a singleconstellation at a time & fall baông chồng to lớn others if that constellation does not have enoughvisible satellites.) The order of preference is market dependent, however it is mostly GPS,then GLONASS & then BEIODU. As of the beginning of 2017 only a few phones supportthe GALILEO constellation. If you have problems getting a fix, please read the FAQfor troubleshoothing tips.
The compass needle (C) in the center of the grid will show you the direction of themagnetic field as measured by your phone. (This may or may not be the actual magnetic north,depending on how much extra magnetic field is present in your environment. Magnetic anomaliesare always present in buildings & vehicles so you should NOT expect your compass towork flawlessly in these environments.) The program automatically calculates the magneticdeclination (the difference between magnetic and true north) and the absolute strength ofthe magnetic field at your current location (M). If the measured field is strongerthan the calculated you will see the needle grow while with weaker fields the needle willshrink. If there are no extra magnetic fields in your environment the needle should be roughlythe same form size as the inner circle of the sky grid. In addition to lớn this, the magnetic compassin your phone reports the accuracy of the measurement.
If the needle gets transparent (or you see a question mark appearing in the magneticfield reading instrument) then the compass may need a recalibration (in the side navigationCompass Calibration menu). The recalibrationcan be done any time the app is running (i.e. you don”t need to enter the “Calibration” dialog,however that dialog displays the accuracy reported by the phone so you will get a bit betterfeedbaông xã.) You can recalibrate by either rotation your phone several times along its 3 axes(as instructed in the dialog), or by less scientifically, just simply holding your phone andwaving it in an 8 pattern. You should chạy thử which method works best as it is also dependent onthe actual firmware of the phone.
Magnetic compasses are inherently inaccurate. GPS can bởi vì a much better job determining yourdirection of movement. By mặc định the sky grid aligns itself using the magnetic compass.Once you move sầu faster than 5km/h a green arrow will appear showing your direction of movementand the sky grid will align using the much more accurate GPS heading data. The red/xanh arrows(W) around the perimeter of the grid show the true north/south while the red/xanh dots(X) show the magnetic north/south. The difference between the two direction is known asthe magnetic declination (M).
There is a small empty circle (Y) (can be turned off in Settings) that allows you to find the direction of any satellite. Just turn và tilt your phone until the circle covers a satellite symbol. Your phone will point towards the real satellite that is some 20000 km away from you. (This feature is not particularly useful, but it is extremely geeky!)
The grid also contains a moving amber circle (can be turned off in Settings). This canbe used as a leveling tool (L) to lớn find horizontal or vertical surfaces using your phone.You may need khổng lồ calibrate the leveling tool before using it (in the side navigation menu).
In the PRO version, the rotation speed (R) of the phone is also displayed along theperimeter of the sky grid. The longer the green arcs, the faster the phone is rotating.
The signal strength bars (V) show the individual satellite signal strength values.The bar is divided into lớn 4 parts displaying GPS, GLONASS, BEIDOU và GALILEO sats (left to lớn right).
The rest of the screen displays numerical values derived from the phone’s sensors và GPS.
Heading (H): the absolute direction the phone is facingOrientation (O): main cardinal points your phone is heading currentlyaGPS data age (E): the age of the GPS assistance data used for speeding up the GPS locks.Error (E): the accuracy of the actual location information.Number of satellites (F): the number of satellites used for the actual fix and the total number of satellites visible for the GPS receiver (GPS+GLONASS/total.)Pitch and Roll (L): the attitude of your phone.Magnetic field (M): the three values represent the strength of measured magnetic field / the calculated strength of the field / magnetic declination (the difference between true and magnetic north). (Tip: the first slash will turn inlớn a question mark if the phone detects that you have to lớn recalibrate the phone’s magnetometer.)Acceleration (Z): the measured linear acceleration of the phone.Speed (S): the actual tốc độ measured by the GPS.Altitude (A): the current altitude relative to lớn the Mean Sea Level (MSL) or the WGS84 geoid (configured in Settings).Last fix (I): the GPS time of the last valide fix that is shown currently on the screen.Location (latitude/longitude) (J): The acquired GPS location (format is configured in Settings).Battery info (B): the remaining charge, battery voltage and temperature.DOP.. (dilution of precision) (D): a value that represents how optimal the satellite constellation is. Smaller values represent better satellite arrangement. The total, horizontal và vertical component is also displayed.Brightness (K): the measured light flux (if the phone supports it). The accuracy of this value is dependent on the quality of the brightness sensor.Pressure (P) PRO>: atmospheric pressure measured by the phone sensor (if the phone supports it).Rotation tốc độ (R) PRO>: this is the direct readout from the phone’s gyroscope sensor (if the phone supports it).Ambient temperature (T) PRO>: the temperature around the phone (available only on Galaxy S4 & Note3).Dewpoint (N) PRO>: the temperature below which water vapor will start condense (available only on Galaxy S4 & Note3).Humidity (Q) PRO>: the amount of water vapor in the air (available only on Galaxy S4 & Note3).Humidex (U) PRO>: an index that shows how hot the weather feels lớn the average person (available only on Galaxy S4 & Note3).
By mặc định, the application will show the most important GPS data whenever theGPS is accesses, even if other apps accessing it.
If you vì not need the notification feature, you can turn it off inSettings / Background Behavior / GPS Status in Notification -> Never.

Tapping on the notification tác phẩm will open GPS Status. This is an easy way lớn open the phầm mềm from any other application that is using the GPS. Wait for the lock in GPS Status then press the baông xã button to immediately return khổng lồ the original application without loosing the lochồng. The notification have some extra actions that allows you lớn dismiss it temporarily, re-tải về the aGPS data, or mark your current position for future use.
This feature uses little lớn no battery as the notification is updated only when it is shown. The display routine does NOT access or keep the GPS open. It just intercepts the location data that is requested by the other application. GPS Status never keeps the GPS open if it was put into lớn the background.
Radar screen can store a single way point (Edit/Mark action button) và allows you to navigate baông xã using the GPS & the internal compass in your phone. Just move sầu towards the point and use the screen as it would be a “radar”. The radar screen will display heading and distance to lớn the target point. It is possible lớn enter or edit the target coordinates và you can also chia sẻ your current location by using the Share action. The marked point can be displayed in any of the supported mapping applications. Additional waypoints can be displayed on the radar if you change the given waypoint”s visibility on the Locations screen (tap the eye icon).
Long tapping the Edit/Mark mark location button will immediately store the current location as a target (& will override the previous target without displaying a dialog). This is useful to drop a breadcrumb so you will be able khổng lồ get baông chồng here later (i.e. after parking a car etc.)
Heading (H): the absolute direction the phone is facing.Orientation (O): main cardinal points your phone is heading currently.Compass needle (C): magnetic compass needle.Error (E): the accuracy of the actual location information.Distance (D) : distance to lớn the current target point.Accuracy range (F) : the current position accuracy shown as a range around the actual position.Target (latitude/longitude) (L): the coordinates of the currently selected target point.Speed (S): the actual speed.Altitude (A): the current altitude relative sầu to the Mean Sea Level (MSL) or the WGS84 geoid (configured in Settings).Bearing (B) : Bearing to lớn the target pointLocation (latitude/longitude) (J): the current location.Target point (T) : the target point shown on the radar grid relative to the current position.Additional waypoints (W) PRO>: additional waypoints selected on the Locations screen.
This screen allows you lớn store 3 waypoints persistently (unlimited in PRO version).Long tapping an tòa tháp puts the menu into edit mode where you can select more items orreorder them. After selecting items you can export them by choosing the “Export”vật phẩm the action bar. Importing in KML, CSV & GPX format is also available here.
Waypoints can be added either from the Radar screen by opening the Edit targetdialog & choosing “Save sầu as POI” or by tapping the “Add location” button on the”Locations” screen. You can assign a color lớn the point. You can edit an item bytapping on it. The Edit dialog allows you to select the given point as a targeton the Radar screen.
This screen can be used for troubleshooting phone sensor issues. It displaysall possible sensors và marks the ones that are actually supported by yourdevice. It also tries lớn acquire some values from the sensors to lớn seewhether they are working correctly. If you see error marks on the menu,tap the entry and follow the instruction lớn chạy thử the given sensors properly.
Display units, UI language, sensor filtering, color scheme, message used for sharingyour location và a bunch of other options can be configured lớn customize theapplication. chú ý that GPS Status is using the WGS84 datum whenever coordinates are used.
