SigTrax is an app for Android and IOS devices that significantly reduces the time and effort required to locate an object by combining the technique of triangular location with the power, services and visual capabilities of mobile devices. SigTrax enhances the triangulation process by eliminating the manual handling of maps, plotting intersection points and determining the route to reach an intersection point, resulting in more accurate, convenient and faster searches.
Whether it is an ham radio (amateur radio) fox hunt, searching for signal interference (RFI), seeking out an unlicensed (pirate) radio signal, tracking near-space balloon flights, finding a transponder, tagged wild life tracking, finding a lost quadcCopter or a search and rescue mission, SigTrax simplifies and speeds the search process.
An estimation of the direction to an object is called a Bearing. Determining where bearings intersect is the process of using triangular location to locate the object.
Creating a Bearing is easy with SigTrax. Pressing either side of the Rotation Ring rotates the map image and updates the compass heading. When the desired compass heading is reached, pressing the User Location (normally blue) displays a bearing guide line on the map. After the quide line appears, press the 'Yes' button to create the new Bearing.
A Bearing will be created starting at the device location pointing toward the target object. If the user location ring is not visible, tapping the Location icon will center the map on the device location. Other Bearings can be created by moving to another location and creating a new Bearing or by manually entering a Bearing coordinates by pressing the 'Bearing' button.
Coordinates can be viewed and entered using Geodetic Coordinates (Latitude and Longitude), UTM and MGRS.
Location is determined by location information returned by the device's cell network and GPS. GPS will always be more accurate but requires a clear overhead view and may not function well inside a closed space. The locator ring that marks the current location of the device serves as an indicator of the last known location accuracy.
Detailed information on the accuracy of the last known location can be obtained by pressing and holding SigTrax's Location button.
There are two reasons why the Rotation Shuttle controls may not be visible. The contols are only visible if "Map Rotation" is set to "Manual" in Settings. In addition, if a Bearing or Crosspoint is being view the map is locked to True North with the heading background in red and the Rotation Shuttle is not visible.
SigTrax uses "True North" centered on the North Pole rather than "Magnetic North", centered on magnetic north, True North is used by the mapping service to orientate the drawn map. The difference between True North and Magnetic North is known as the declination and varies by location.
SigTrax shows both headings based on the declination at the device location. True North is displayed in the command bar while Magnetic North is displayed immediately below.
SigTrax requres the use of the network receiver and GPS for location determination and the magnetic sensors of the device for heading determination. Each of these sensors consumes battery power. It is the responsibility of the user to insure that sufficient battery power exists to operate the phone in the event of an emergency.
SigTrax's battery consumption can be altered by changing the Compass and Location update rates in Setttings and exiting the app when not being used.

SigTrax is available for Andriod and IOS based devices and can be downloaded from the Google Play Store and the Apple AppStore.
System requirements include GPS and Internet access for downloading maps.
If you cannot find SigTrax when searching on an app store that may be an indication that your device does not support the features required by SigTrax. iPads without the cellular option will not be able to download SigTrax as they lack the required GPS and compass components.
The rotating compass heading feature can only be used with devices that contain a magnetic field sensor. Some lower price Android devices eliminate this sensor. SigTrax will work on these devices but the compass heading option is disabled.
For proper operation, the device must be located where a GPS signal can be received and Internet access for downloading the maps.
SigTrax does not record, maintain or transmit any device location information. SigTrax uses the facilities of mapping services that may record or track device location information.
