GPS Trip Analyzer

收集并分析GPS数据。包括图，地图，旅行的分析。

The purpose of this app is to build a detailed post-trip analysis of collected GPS data including speed, elevation, bearing, time, number of satellites, satellite signal strength, time between GPS readings, distance between GPS readings, reported accuracy, gradient, and latitude / longitude.

You can track hundreds of trips and view them by date (from a calendar) and by category (cycling, walking, or jogging). For each trip, the start time, end time, distance covered and the minimum / maximum / average for the following parameters - elevation, speed, accuracy, time in seconds between GPS readings, and the distance between GPS readings will be computed.

For every GPS reading, the latitude, longitude, battery level, timestamp, altitude, speed, bearing, accuracy, gradient, GPS satellite signal strength, and number of GPS satellites used for the reading will be saved.

For each trip, you can view the track on a Google Map. The color on a segment of the track will depend on the speed, altitude, or gradient.

You can view ten different plots showing the speed, altitude, battery level, gradient, number of satellites, satellite signal, pace, time and distance between readings.

The GPS track can be played back and forward to view the distance covered and pace at any time during the trip. A GPS reading can be dragged to a correct location on a Google map to fix location errors near a bend on a trip.

Two trips from the same route can be compared side by side to view differences in speed at various locations.

Export and import trips using the GPX format. Any exported trip can be viewed using a Web or app based GPX visualizer. You can backup and import hundreds of trips in the GPX format.

Check a map of the number of satellites available to get GPS readings and monitor signal strength. Change the GPS setting for higher or lower precision and optionally send SMSes of the current locations at specified intervals.
