DOUBLE CONSTELLATION GPS+GLONASS LAP TIMER with INTERMEDIATES
IDEAL TIME - GPS SPEED - HOUR METER - LAP TIMES AND MAX SPEED PER LAP

COMPACT WITH HIGH READABILITY

STEALTH GPS-4 Lite is an extremely compact GPS laptimer but equipped with a large character display to allow maximum readability during demanding driving. Its small size allows it to be easily placed on the bike.
(width 90 mm - height 45 mm - depth 18 mm).

DOWNLOAD LAPTIMES ON USB PENDRIVE

STEALTH GPS-4 LITE allows the download of the times and maximum speeds of each lap directly on your USB pendrive, this solution makes it possible to use it without the need to bring the computer to the track. The MAAT software will automatically recognize your USB key and downloaded sessions.

INTEGRATED LIBRARY WITH OVER 1000 TRACKS

Allows the immediate use thanks to the built-in library of over 1000 tracks with intermediates, between which the device automatically recognizes the current one. In the remote case that your track is not included in the library, the SAFD-2 (Starlane Automatic Finish line Detection) function will automatically divide the track after the first 2 laps, allowing you to see your times and splits, already from the first session without intervening on the laptimer.

OPTIONAL TRAJECTORY ACQUISITION

At any time you can bring your Stealth GPS-4 Lite to the Lite + version simply by making the paid upgrade on the website.
The Lite + version equates it to the normal Stealth GPS-4, activating its graphic data and trajectories acquisition functions and allowing the expandability with the optional RID modules, for the acquisition of vehicle data.

LEAN ANGLE INDICATION AS AN OPTION

Inertial Pack performs the calculation and indication of:

  • LEAN ANGLE
  • LATERAL ACCELERATION in G
  • LONGITUDINAL ACCELERATION in G

The analysis software also shows the acceleration and lean angle charts (in case you also upgraded the system from lite to Full version).

The system calculates the lean angle relative to the axis (B) passing through the center of gravity of the motorcycle + rider, considering also the rider position.

The lean angle is calculated by a high precision algorithm developed by Starlane and does not require the installation of sensors on the vehicle.
Unlike other systems, it also allows correct angle alignment and acceleration with the instantaneous position on the circuit.

You can see the lean angle degrees on the specific screen page which indicates
the current angle and the maximum degrees reached in the last right and left corners.

ATTENTION: THE LITE VERSION DOESN'T RECORD TRAJECTORIES AND DOESN'T SUPPORT RID EXPANSION MODULES TILL YOU UPGRADE IT TO FULL VERSION.

1) DOUBLE CONSTELLATION GPS+GLONASS RECEIVER AND ANTENNA BUILT IN THE INSTRUMENT:
the Stealth shock-proof ABS body accommodates the new double constellation receiver which uses in symbiosis the american GPS and the russian GLONASS satellite systems. This solution increases dramatically the precision due to the vero high number of satellite involved in instantaneous position, speed, trajectory and lap time determination.

2) YOU CAN SAY GOOD-BYE TO ALL UNPRACTICAL INFRARED TRANSMITTERS ARRANGED ON THE PIT WALL:
the use of the GPS+GLONASS system intended to detect the lap time will make STEALTH GPS-4 LITE completely autonomous, requiring no beacon transmitters, such as the infrared ones used by old-generation systems.
Everything is getting much simpler. It is no longer necessary to arrange the transmitter and to recharge the battery, which is extremely annoying and unpractical, with the risk of forgetting it on the wall or having it stolen.

3) MANAGEMENT OF THE FINISH LINE AND 3 INTERMEDIATES:
you can set up the coordinates of 4 trigger lines (main finish line + 3 optional intermediates). Whenever you cross a finish line or an intermediate, STEALTH GPS-4 LITE will indicate the relative split time and store its value. You can therefore quickly evaluate your own performance even if you are driving along a part of the track far from the main straight stretch, which would be expensive and unpractical if you used any other type of lap timer.

4) INDICATION OF THE ACHIEVABLE IDEAL TIME:
by managing intermediates, STEALTH GPS-4 LITE can calculate the time a driver can ideally achieve for every single session. This function is obtained by adding the best sectorial times. This will help you understand the lap time you might have achieved if there had been no traffic in a specific point of the track or if you had done a lap on top of your absolute performance.

5) DOUBLE FUNCTION "BEST LAP" LED:
the "BEST LAP" LED will turn on if you have improved your previous lap and it will blink if the lap you have just done is the best of the session. This solution will supply the driver with all the information necessary for performance without any distraction.
If you have set up intermediate finish lines, the LED is also enabled whenever you cross an intermediate. This means that this instrument is extremely useful to realise without any distraction whether you are improving compared to the same intermediate time of the previous lap or whether you have just accomplished the best intermediate time of the session.

6) GPS SPEED MEASUREMENT:
the advantage of using a GPS+GLONASS system is also that you can measure the vehicle speed with the highest degree of accuracy without having to install any sensor on the vehicle. No user setup is required and, above all, any measurement is always accurate, not altered by the inclination of the vehicle or wheel spinning.

7) DOUBLE HOUR METER FOR THE PERFECT PERIODICAL MAINTENANCE OF THE VEHICLE:
STEALTH GPS-4 LITE has also got two hourmeters that can be separately reset for the periodical maintenance of the vehicle. Hour Meters are activated to receive the GPS speed signal. This solution can operate the hour Meters without any connection to vehicle harness.

8) LAPTIMES AND MAXIMUM SPEED DOWNLOAD TO USB PENDRIVE:
STEALTH GPS-4 LITE fits a wired USB socket, that can be easily positioned into the fairing, in which you can plug any USB flash memory.
This solution makes the system totally free form the computer, at the end of the track day you will just need to plug the USB pendrive and Stealth GPS-4 LITE will download the acquired laptimes and maximum speeds for each lap, that will be then analyzed directly into the software Digirace-MMX.

9) 999-LAP MEMORY WITH AUTOMATIC MANAGEMENT OF 99 TEST SESSIONS:
STEALTH GPS-4 LITE will automatically create a new session whenever you access the track. This means that you can analyse the times you have stored during the various sessions even at the end of the day without having to delete memory whenever you access the track. You can store the Date and Time of every single session as well as the total time, the intermediates, the maximum speed for every single lap.

10) CYCLICAL MEMORY MANAGEMENT:
with STEALTH GPS-4 LITE you will never face memory full issues because,in order to allow a continuous usage, it manages the available space by erasing automatically the oldest sessions when the memory is almost full.

11) STORAGE OF THE FINISH LINE COORDINATES OF THE TRACKS MOST USED:
you can store the coordinates acquired for the finish line of the tracks you are training on most frequently. You can file up to 16 tracks and easily call the finish line of the current track without having to reset it every time.

12) STEALTH GPS-4 LITE IS COMPLETE WITH A BACKLIT LARGE-SIZE GRAPHICAL DISPLAY:
this solution has provided for the development of a software unit that can analyse all stored data and set up all wished functions in an unequally user-friendly and immediate manner. The display is of a transflective type, which means maximum visibility also in the sunlight when backlighting is off.

13) EXTERNAL SUPPLY:
supplied by 12V vehicle battery or by optional cases for 9V batteries or optional batteries. Moreover, STEALTH GPS-4 is complete with powerful energy saving and self power-off functions the user can set up to make the best use of battery performance. It is supplied with a specific extension with eyelets for battery connection and with a connector on one side of the instrument for rapid disconnection.

14) WATER-RESISTANCE:
STEALTH GPS-4 is water resistant and it can also be used in case of rain.
