Every day Sporttraxx is developing and improving its hardware and software solutions for:
We also call it Passive GPS Tracking. When we continuosly log GPS positioning and timing data of a vehicle, a boat, a man.
By simply carrying/wearing the smallest tracking device we collect in its internal memory, informations as
- Height above sea level
- Time and Date
Other data like Waypoint marking, Time stamps, GPIO status, Alarms, Satellite's visibility and its field strength can also be stored, according to the hardware features
The logger parameters, frequency and filters can easily be setup via software, according to the needs of each sport discipline and its rules.
The collected data are downloaded, wireless or via cable, during or at the end of the sportive performance. The accuracy of the data is calculated in meters and in parts of seconds.
Typical sports applications are:
Control of the respect of rules and tracks
Highlight of shortcuts, cheatings and illegal servicing
Timing or timing backup
Investigation on accidents and rescue actions.
For the immediate and fully automatic evaluation of the data, several different applications have been created by Sporttraxx. With mapping interfaces or electronic datasheets.
Sporttraxx reports what a competitor has done. Where he has been, when, how and for how long... All that is recorded in a GPS Logger
Live Active GPS Tracking. GPS data are transmitted in real time, at set time intervals or according to specific conditions.
Transmitting tools can vary depending on the environment, the requested update frequency and the budget.
Data are typically transmitted via:
Live tracking hardware performs also internal logging features and its logging frequency can be at even much higher rate than the transmitted data. Data are saved both inside the unit and in the Sporttraxx internet server.
The system is two-way. That means that not only informations are sent to race headquarter or to Sporttraxx office, but also messages and commands can be sent to the competitor. Voice communication is possible with GPS/Radio and GPS/GSM devices.
GPS provides accurate location in open space, with free view to the sky. Live transmission needs to be in an area covered by the communication technology (inside a radio network area, inside a mobile phone radiocell, on a continent/ocean with satellite coverage).
Radio transmission is mostly used in small local areas.The units can be very small, light, battery operated, for vehicle and personal use.
GSM/GPRS can work worldwide in areas with coverage provided by local mobile phone operators. Units are mostly powered by the vehicle, but can be also be battery operated. Nowadays almost all the inhabited areas offer good GSM coverage.
Inmarsat D+ satellite technology is operating worldwide, with the exclusion of the polar regions. Ideal solution for low frequency activities in deserts and on sea.
Sporttraxx transmitted solutions are based on two types of data carrier:
Online Radio or GPRS, with a continuos connection to the unit, that forwards NMEA data up to each second. The graphical result on maps is an icon moving on the screen on a smooth line, continuosly updated. Eccellent in the detail, it can be used to track up to hundreds of competitors at the same time.
By messages (SMS), transmitting at given intervals, or when reaching defined areas, the single position or packages of positions. The graphical result is an icon on a line with sharp edges, updated and relocated only at each received message from the unit. The frequency of the messages depends mainly on the number of competitors, the duration of the race and its budget. The Inmarsat D+ solution is based on messages with a minimum interval of around 4 minutes. Radio and GSM can be setup to message intervals of few seconds.
Both types of data transmission can be combined during the same event. Most of the events Sporttraxx is tracking, are managed with GPRS technology. All the competitors and the service vehicles are connected online with very high update rate. Messages are generally used only to release alarms or send passage times at PCs (Passage Controls) or on timing lines.
Local networks and Internet
At the very beginning of Sporttraxx activity, the services were offered only on local computers. Passive tracking results were evaluated on Sporttraxxx computers with dedicated and complicated mapping softwares. The first live tracking applications used to work Point to Point. From the vehicle to the Sporttraxx local computer and the data management was possible only for Sporttraxx technicians. Generally in the local headquarter of the event.
Since Sporttraxx introduced in 2005 its GPRS Live Tracking Solution, the sharing options have increased significantly. Everything is going through Internet and that allows multilocation. Data and alarms are sent from the competitor directly to Sporttraxx Servers in Germany, where they are processed and then spread around worldwide. Each computer connected to the internet can access those data. With no need of dedicated and complicated softwares. Obviously Sporttraxx can assign different access levels to whom is managing the event rather then just following it for fun. A more comprehensive description of this solution can be found here.
The Live Show
The most significant result of this new internet based solution is that the event can finally be followed and appreciated worldwide. Especially those Sports like Enduro, Rallying, Sailing and whatever is running far away from the crowds and the civized areas can now involve many more spectators and sponsors.
Internet makes it now possible to virtually fly above the rally car of the loved champion, speeding at 200 km/h in the desert of Qatar....Just sitting in a confortable chair in London.
Sporttraxx shows what a competitor is doing. Where he is right now, at what speed he is moving, if he is OK or needs help ... All that is transmitted from a GPS Live Traxxer
