Quickly and easily determine a remote GPS location from two, or more, geolocated points with compass bearings to that location. Specifically designed for use in the field, Field Triangulate supports: - Fully automated use of iOS device location. Compass bearings are best manually entered. - Manual entry/edit of any/all readings. - On map display in various display modes. - Manually update device bearings (e.g. for use with a compass.) - Share the triangulation to others. - Multiple latitude/longitude formats: -- Decimal degrees -- Degrees and decimal minutes -- Degrees, minutes and seconds. -- (Display for UTM.) Basic usage: Use your iOS device & compass to take bearing on a remote location from two locations and Field Triangulate will calculate and display the GPS coordinate for the remote location. Advanced usage: Enter readings provided from a remote person (perhaps by iPhone or radio) and add your own readings manually in order to calculate a remote location.

Signal Tracking Toolkit SigTrax is the signal tracker’s toolkit combining the power and visual capabilities of IOS mobile devices with high precision GPS locating and hand held mapping to plot bearings and determine Crosspoints™, locations where bearing lines cross, potentially the location of a signal’s origin. THE SIGTRAX DIFFERENCE Signal tracking has always been a vital resource, assisting in emergency situations,locating interference or noise sources and serving as a valuable asset for spectrum monitoring. SigTrax expands this resource by supplying tools that allow signal trackers to find the origin of signals faster with more accurate results. SIMPLIFY THE TRACKING PROCESS The advent of mobile smart devices allows us to have tools that before were either non-existent or like the signal trackers collection of papers, maps and marking instruments, unwieldy to carry and use. With SigTrax, manually handling maps, plotting intersection points and determining a route to reach an intersection point is eliminated, simplifying searches resulting in faster and more accurate results. BEARINGS AND CROSSPOINTS™ Bearings are lines from a starting coordinate toward a compass heading as an indication of the approximate direction of a signal. Bearings can be entered into SigTrax in multiple ways, selectively viewed, edited or deleted. Bearing collections can be archived then retrieved at a later time, vital when tracking signals over long time periods. Crosspoints, locations where bearing lines intersect, are automatically managed when bearings are added, deleted or edited. Driving maps complete with text and voice routing instructions direct the user to a Crosspoint location. EASY TO USE The SigTrax user interface was designed to be simple and easy to use in less than ideal conditions. SigTrax can be customized to individual preferences and needs using the Settings function. A complete User Guide is included for quick reference. SigTrax+ OPTIONAL FEATURES SigTrax+ optional purchasable features expand the signal tracking toolkit. SigShare™ allows bearings and archives to be displayed in a large format such as Google Earth, ideal for presentations. DataTrax™ is a smart interface that automatically inserts and plots bearing generated from external systems such as Doppler. The SigTrax website details DataTrax features and requirement. TraxTeam™ allows cooperative hunting, a foundation of signal tracking, that greatly extends the possibility of a successful and timely hunt, vital in emergency situations. Multiple trackers form a TraxTeam™ instantaneously sharing bearing information with the hunt group. REQUIREMENTS Requires IOS device with GPS and internet access to obtain map images.
