Multitracking

QuoVadis 7.3 offers in multitracking (object tracking) different possibilities to track (technical) objects. The surface for this in QV7.3 always shows the same display of the position, regardless of the technique used. An object can be displayed on any map available in QV7.3. However, there are large differences in the frequency of positioning, coverage and costs for the hardware used. The ultimate technology, with which any application can be killed, does not exist. It must therefore be checked in each individual case which requirements are to be fulfilled and which technology is most likely to achieve the goal set. Here we try to briefly describe the different possibilities.

We ask for your understanding that the possibilities described in the following, in part, require considerable prior knowledge in the selection and procurement of hardware, setting up networks, programming work, understanding of mobile radio types and ranges. We are not able to provide detailed advice free of charge beyond setting up the interface in QV/QVM. Simply contact us, we will be happy to submit you an offer within the scope of a consulting order.

Solutions for receiving position data (Host)

“SPOT Messenger: In our opinion, the satellite tracker SPOT currently offers an unbeatable price/performance ratio with almost worldwide coverage. If you have purchased a SPOT Tracker and registered an account with SPOT, you can query the positions received on the SPOT server with QV7.3-PU. It goes without saying that the SPOT Tracker should be attached to the object in an exposed position. However, we were very surprised that our SPOT Tracker was able to connect to the SPOT Satellite from the top of the dashboard without any problems.

Depending only on the establishment of a connection to SPOT satellites, which meanwhile have an almost worldwide coverage, no roaming problems, fixed costs consist of hardware and registration. The possible tracking intervals are between 2 and 5 minutes (depending on the contract).

“QVX(QVM) shared locations.” These are position messages of our mobile apps, QVM-i V3, QVM-A V3, QVM-W V2) which are stored in the cloud (Azure Server) and can be queried with QV7.3-PU.

Depending on the establishment of an Internet connection - cross-border problems and considerable costs (roaming) can occur. You have to find out exactly what the Internet coverage looks like in the desired area. The shortest possible tracking interval is 1 minute.

“GSM/SMS”: A tracker with SIM card sends position data via SMS to a GSM modem connected to the computer with QV7.3PU. QV reads the incoming SMS and displays the positions. QV7.3-PU has integrated adjustment options for the format of the position report in order to be able to adjust as many different formats as possible.

Depending on the establishment of an Internet connection - problems and considerable costs (roaming) can occur across countries, one must inform oneself exactly how it looks like in the desired area with the Internet coverage. The shortest possible tracking interval is 30 seconds. The coverage of the GSM network required to send SMS is significantly better than the mobile coverage via Edge/G3/G4. As a rule, you get position messages via SMS even in places where “nothing works” via Edge/G3/G4 for a long time.

“QV Tracking Gateway: The gateway is a database on one of our servers that can record the positions via http from SANAV trackers (in their internal format) or from any other client that can send a position via http in $QVPOS (similar to NMEA record) format. This can be any hardware or application. Interested parties can program hardware to meet this requirement, or program applications (software clients) in connection with their own position reporting systems (BOS…), which can then supply the gateway with position data. The QV-Tracking Gateway can then be queried with QV7.3-PU and displays all positions stored on the Gateway since the last query. QV7.3-PU does not have to run permanently to display the complete course of a route.

Depending on the establishment of an Internet connection - problems and considerable costs (roaming) can occur across countries; you need to find out exactly what the desired area of Internet coverage looks like. The shortest possible tracking interval is 30 seconds per position transmission. The QV-Tracking Gateway is subject to a fee per tracked object.

“File polling: A highly interesting and very flexible variant is “file polling”. Any third-party application that receives position data, however, decodes it and stores the position data with a specific format ($QVPOS) in files that follow a specific naming scheme. This can be in a local directory, a networked directory or on a web server where QV7.3-PU has access (via FTP if necessary). QV7.3-PU looks in this directory at definable intervals, reads in newly received positions and displays them. Used by authorities, police and military if the position report is encrypted and decoding cannot be given “out of house”.

No costs in the local network, connection costs can arise via WAN. Coverage depends on the range of the hardware used. Tracking interval, whatever the hardware is capable of, practicable min. 10 seconds.

“Serial port: z. B. for use with radio decoders, i.e. radio receivers which extract a position message from a radio signal and transmit it to a computer via a serial connection. QV7.3-PU can process NMEA, AIS or APRS signals.

No costs in the local radio network, depending on the range of the equipment. Tracking interval whatever the hardware is capable of, practicable min. 10 seconds

“TCP socket: QV7.3-PU can evaluate position messages which are sent to a certain adjustable port via a network connection. These positions can be entered via the local LAN, (Ethernet/WLAN) or WAN. The configuration of the hardware involved requires very good network knowledge.

No costs in local wireless network, connection costs in WAN possible. Coverage depends on the range of the hardware used. Tracking interval, whatever the hardware is capable of, practicable min. 10 seconds.

“Garmin Astro: From older Garmin Astro devices, positions tracked with the Astro can be read here. Real “handicraft solution”, since Garmin never intended it that way and according to our information with newer Garmin Astro also no longer possible.

No costs in the local wireless network, coverage depends on the range of the hardware used. Tracking interval, whatever the hardware is capable of, practicable min. 10 seconds.

“GPS gate: here a connection to the Franson GPSGate http://www.gpsgate.com/ can be established. The prerequisite is that you have registered an account there.

No costs in the local network, connection costs can arise via WAN. Coverage depends on the range of the hardware used. The shortest possible tracking interval is 20 seconds.

“QVM WP8 GPS locations.” This variant should not play a role any more and was only briefly in the first version of QVM-W has been replaced by “QVX(QVM) shared locations” for all QVM V2/V3 Apps.

Tracking with QuoVadis Mobile V2/V3 as client (transmitter): all current QuoVadis Mobile Apps can store their position in the cloud (Azure server), the positions can be shared by a single device with QVM or also in a group of devices with QVM among each other and also fetched by QV7.3-PU.

Tracking with QuoVadis 7.3 as client (transmitter): There is also the possibility that a running Quovadis 7.3 Poweruser redirects positions it has received via a connected GPS receiver. QV7.3 PU can connect positions to the QV tracking gateway (see above), in the QVX(QVM) system to the cloud, and to a GPS gateway account from Franson. Furthermore, QV7.3-PU can also store position data with structured content ($QVPOS), store in a local directory, a networked directory or via FTP on a web server according to a specific naming scheme
