Multitracking

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

We ask for your understanding that the possibilities described below partly require a not inconsiderable previous knowledge in the selection and procurement of hardware, setting up networks, programming work, understanding of mobile phone types and ranges. We cannot provide any detailed advice free of charge beyond the setup of the interface in QV/QVM. Just contact us, we will be happy to make you an offer within the scope of a consulting assignment.

Solutions for receiving position data (host)

“SPOT messenger.” In our opinion, the SPOT satellite tracker 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 use QV7.3-PU to query the positions received on the SPOT server. It goes without saying that the SPOT Tracker should be placed in an exposed position on the object. However, we were very surprised that our SPOT Tracker was able to connect to the SPOT satellite without any problems from a concealed shelf on top of the dashboard of our vehicle.

Dependent solely on establishing a connection to SPOT satellites, which now have 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 reports from our mobile apps (QVM-i V3, QVM-A V3, QVM-W V2) that are stored in the cloud (Azure Server) and can be queried with QV7.3-PU.

Depending on the establishment of an Internet connection - cross-national - problems and considerable costs (roaming) may occur. It is necessary to find out exactly how 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 customization options for the format of the position report to be able to adapt as many different formats as possible.

Depending on the establishment of an Internet connection - Cross-border, there can be problems and considerable costs (roaming), you have to find out exactly what the Internet coverage is in the desired area. The shortest possible tracking interval is 30 seconds. The coverage of the GSM network needed to send SMS is much better than the coverage of the mobile network via Edge/G3/G4. As a rule, one receives position reports via SMS even in places where “nothing more works” via Edge/G3/G4 for a long time.

“QV Tracking Gateway.” The gateway is a database on one of our servers that can receive 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. So QV7.3-PU does not have to run permanently to display the complete course of a track.

Depending on the establishment of an Internet connection - Cross-border, there can be problems and considerable costs (roaming), you have to find out exactly how the Internet coverage looks like in the desired area. The shortest possible tracking interval is 30 seconds per position transmission. The QV-Tracking Gateway is charged 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 certain format ($QVPOS) in files that follow a certain naming scheme. This can be in a local directory, a networked directory or on a webserve 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 the decoding cannot be given “out of house”.

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

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

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

“TCP socket.” Here QV7.3-PU can evaluate position messages sent via a network connection to a certain adjustable port. 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 the local radio network, connection costs in the WAN possible. Coverage depends on the range of the hardware used. Tracking interval, whatever the hardware provides, practical min. 10 seconds.

“Garmin Astro.” From older Garmin Astro devices you can read out tracked positions with Astro. Real “craft solution”, because Garmin never intended it that way and according to our information it is not possible with newer Garmin Astro.

No costs in the local wireless network, coverage depends on the range of the hardware used. Tracking interval, whatever the hardware provides, practical 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 a corresponding account there.

No costs in the local network, via WAN connection costs can arise. 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 anymore and was only briefly in the first version of QVM-W was 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 even in a group of devices with QVM and can also be picked up by QV7.3-PU.

Tracking with QuoVadis 7.3 as client (sender): Furthermore, it is also possible that a running Quovadis 7.3 power user is able to forward positions that it has received from a connected GPS receiver. QV7.3 PU can send 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) according to a certain naming scheme in a local directory, a network directory or via FTP on a web server
