GPS location and tracking
Many popular services such as taxi companies, post offices and shipping companies often use GPS tracking features to optimize their operations in the field. T.Flex has an integrated service which integrates GPS tracking capabilities with the built-in map. To access the GPS location and tracking interface, tap Map in the main menu. You can do the following on the map:
- Zoom in and out
- Switch to detailed street view
- View the precise positions of TASSTA users and locate them
- View the "who is talking" status and identify users
- Center on a specific user
- Configure the GPS view
- Use indoor localization features
User identification and markers
The position of each subscriber is marked by an icon on the map with a label that shows the user name.
The user's icon changes status changes when the user presses PTT and the floor is granted. The set of icons is as follows:
|Your last known location|
|You are talking|
|Location where you were last seen talking|
|User's last known location|
|User is talking|
|Location where user was last seen talking|
|User is in emergency|
|User's coordinates are unknown|
|User with unknown coordinates is talking|
In addition to the icons listed above, there is a set of icons with the same meanings for radio users connected to the TASSTA network through bridge middleware. These icons have a pin, as in the following example:
The last known location icons are displayed in two cases:
- The user has gone offline. The user icon will immediately change to the last known location icon.
- The user turned off the GPS. The user icon will change to the previous location icon only after a timeout that is configured by the administrator in T.Commander.
Some users who are online may be absent from the map. This normally means the administrator has turned off GPS location sharing for these users. However, when such a user makes an emergency call, their GPS coordinates are sent to all users that they can reach.
Detailed street view
It is important to have a detailed street view on the map. The integrated map provides a detailed street view with house numbers, road and street names and provides the address of any location.
Furthermore, the map shows colored lines, areas and other standard symbols to help read and interpret the map at different scales.
Real-time positioning and precise location on the map
There are many publications and articles on the Internet devoted to the accuracy of GPS on mobile phones. Some of them introduce us to new technologies improving the accuracy of GPS receivers on phones. Some articles describe the test results for specific mobile phones and even explain the math behind the process. These materials are good to keep in mind, but the best practice is always to test.
Our tests and practical experience allow us to say that today embedded GPS receivers in many existing mobile phones not only meet but also exceed most of the requirements for production use.
The map component of T.Flex has powerful user locating features. On the T.Flex map you can see your TASSTA network users' locations in real time, accurate to the street and house number.
Centering the map on a user
To directly jump to a specific user's location without scrolling the map around, go to the user list, locate the user and tap the Center on map icon for that user. This feature becomes indispensable if you have hundreds of users in your TASSTA network.
To jump to your own location, tap the On map icon, which is located above the map view.
Hiding users from other channels
To hide users that are not in your channel, tap the More icon in the top bar and select Current channel only.
T.Flex provides features for organizing, logging and performing guard tours and security patrols, helping you accomplish your tasks within predefined time intervals.
The routes for the guard tours are configured and assigned by the T.Rodon operator. T.Flex is responsible for helping you track your progress on the tour and providing ways to pass checkpoints.
The following methods are supported for passing a checkpoint:
Simply arrive in the vicinity of the checkpoint
Scan a QR code located at the checkpoint
Tap an NFC tag located at the checkpoint
When a guard tour is assigned to you by the T.Rodon operator, you get a notification and a shield icon is displayed.
To view your guard tours on the map, tap the More icon in the top bar and select Guard tours.
To view the details and keep track of your guard tours, select Guard tours in the main menu. In the screen that opens, select the guard tour you need. You can do the following:
- Start the guard tour
Once you have started a guard tour, you cannot cancel it.
- See which checkpoints you have passed and which you have yet to pass
A checkpoint has one of several states: "not visited", "in progress", "paused", "skipped" and "visited". The checkpoint that is "in progress" is the one you currently have to visit next.
- Check the time left for you to reach the next checkpoint
The operator sets timers for passing points (H:MM:SS time format). If you fail to pass the next point before the corresponding timer runs out, a warning is sent to the operator.
- Pass the checkpoint by scanning a QR code if this is a QR-mode guard tour or by tapping an NFC tag if this is an NFC tour.
In this mode, the QR scan and NFC buttons are available in the toolbar in guard tour view. To update your status from a QR code or barcode, tap the QR scan button and scan the code with the camera. To update the status from an NFC tag, tap the NFC button and then tap the the phone on the NFC tag. If the scanned information is valid, your status is updated.
- Pause or resume the tour
- Skip a checkpoint
This action has to be approved by the operator.
- Stop the tour
This action has to be approved by the operator.
