On STEALTH-5, a level of GPS reception tuning and performance has been achieved like never before.
This results in extremely short GPS signal acquisition times and a very high signal-to-noise ratio,
leading to increased accuracy in position calculation and, consequently, in lap time measurement.
Contrary to the widespread misconception that GPS frequency ensures higher accuracy,
the key factor is actually positional accuracy, which allows an efficient algorithm to calculate lap times precisely.
If a system does not have excellent positional detection, increasing the GPS frequency even to 50Hz will only result in 50 samples per second acquired with positional error and therefore incorrect lap times, without any improvement in timing accuracy.
The algorithm developed by Starlane since 2005, when it was the first in the world to launch lap timers with integrated GPS, was already capable of achieving hundredth-of-a-second accuracy even with the low frequencies available at the time, which were 1 or 5Hz.
With the Inertial Pack, the functions for calculating and displaying LEAN ANGLE and LATERAL and LONGITUDINAL ACCELERATIONS in G are enabled.
The MAAT analysis software will therefore also display acceleration and lean angle graphs.
The system calculates the lean angle relative to the axis (B) that passes through the center of gravity
of the bike + rider combination, thus also taking the rider’s position into account.
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 ensures the correct alignment of lean angle and acceleration data with the instantaneous position on the track.
It is possible to view the lean angle on the dedicated screen,
which displays the current angle and the maximum degrees reached in the last right and left turn.
THE DATA ACQUIRED BY STEALTH-5 CAN BE EASILY ANALYZED WITH THE INTUITIVE MAAT SOFTWARE.
The MAAT data analysis software can be downloaded free of charge from the links at the bottom of the page.
Based on the experience gained over the 25 years since the development of the first Stealth generation, the design of the new STEALTH-5 has been refined down to the smallest detail, such as the gasket, which not only provides water sealing but also acts as the elastic part of the SBPS (Starlane Board Pillow System), a true silicone anti-vibration cushion integrated into the housing, exclusive to Starlane and Stealth-5.
This solution, unique in the world, creates an additional barrier against vibrations for the internal electronics, which remain completely suspended and are not fastened with screws to the robust glass-filled nylon outer shell.
In addition to the supplied kit for elastic mounting of the device on the vehicle, this results in strong damping of vibrational stresses that could otherwise severely damage any electronic device.
The SBPS is an exclusive Starlane system, the result of experience gained in addressing the most diverse issues arising from the extreme use of products, where installation plays a crucial role in long-term durability and reliability.
STEALTH-5 supports the technology of optional WID (Wireless Input Device) sensors and wireless modules. The WID modules allow the system to be expanded simply by placing the WID module under the seat, with no need for wiring to bring the signal to the front of the bike, since communication is carried out entirely wirelessly.
In this way, you obtain a professional, complete, and unique data acquisition system, which is fully expandable wirelessly.
This technology, developed by Starlane and thoroughly tested over the past 10 years, has already enabled Corsaro devices to win more than 20 titles in just a few years, across world, European, and national championships.
Dedicated WID modules are available for the latest generation motorcycles, enabling plug & play connection to the bike’s CAN BUS line for the acquisition of the main channels directly from the ECU.

The WID-D wireless module is equipped with a rechargeable internal battery that provides up to 7 days of track autonomy.
The package also includes the cable for RPM, TPS, and wheel speed signals.
The water temperature sensor and the aluminum sleeve for mounting the temperature sensor on the radiator hose are available as options.
Available inputs:
1) BUILT-IN TRIPLE-CONSTELLATION NAVSTAR+GLONASS+GALILEO RECEIVER AND ANTENNA:
The shockproof ABS body of STEALTH-5 houses the new triple-constellation receiver that simultaneously uses satellites from the american NAVSTAR, the russian GLONASS and the european GALILEO systems. This solution greatly increases accuracy thanks to the very high number of satellites used to determine instantaneous position, speed, and lap time.
2) MANAGEMENT OF FINISH LINE AND 3 SPLIT TIMES:
It is possible to set the coordinates of 4 gates (main finish line + 3 optional splits). Each time you pass a gate, STEALTH-5 displays and stores the sector time, allowing you to quickly assess performance even on parts of the track away from the main straight — something costly and impractical with any other type of lap timer.
3) IDEAL LAP TIME INDICATION:
Thanks to split time management, STEALTH-5 calculates the ideal lap time achievable in each session by summing the best sector times. This makes it possible to know what lap time could have been achieved without traffic in a specific part of the track or with a lap performed at the rider’s absolute best.
4) DUAL-FUNCTION "BEST LAP" LED:
The "BEST LAP" LED lights up when improving compared to the previous lap and flashes when the lap just completed is the best of the session. This provides the rider with essential performance feedback without distraction.
If split gates have been set, the LED also activates at each split, making it extremely convenient to instantly know if you are improving over the previous lap’s sector or if you’ve just set the best sector time of the session.
5) GPS SPEED DETECTION:
The advantage of using the GPS+GLONASS system also translates into highly accurate vehicle speed detection without the need to install sensors on the bike. No user setup is required, and most importantly, measurement is always accurate and unaffected by vehicle lean angle or wheel slip.
6) DUAL HOUR METER FOR PERFECT PERIODIC MAINTENANCE:
STEALTH-5 also features two independent resettable hour meters to track periodic vehicle maintenance. The hour meters are triggered by GPS speed detection, making them functional without any connection to the vehicle’s wiring.
7) COMPATIBLE WITH MAAT SOFTWARE:
For trajectory analysis functions, you can always download Starlane’s MAAT software, which enables storage, analysis, and printing of acquired data, along with graphical representation of trajectories including acceleration and braking points, allowing lap-by-lap comparison. The MAAT MOBILE app for Android and iOS is also available.
8) MEMORY FOR 999 LAPS WITH AUTOMATIC MANAGEMENT OF 99 TEST SESSIONS:
STEALTH-5 automatically creates a new session each time you enter the track, allowing you to comfortably analyze lap times across multiple sessions.
Each session stores date and time, along with lap time, split times, and maximum speed for every lap.
9) CYCLIC MEMORY MANAGEMENT:
With STEALTH-5, you’ll never run out of memory. To ensure easy continuous use, it automatically deletes the oldest sessions when memory is nearly full.
10) STORAGE OF FINISH LINE COORDINATES FOR FREQUENTLY USED TRACKS:
It is possible to save the finish line coordinates of your most frequently used tracks. Up to 16 circuits can be stored, making it quick to recall the current track’s finish line without having to reset it each time.
11) STEALTH-5 IS EQUIPPED WITH A BACKLIT GRAPHIC DISPLAY:
This solution has allowed the development of software with unmatched simplicity and immediacy for analyzing stored data and setting user functions. The display is Transflective, ensuring maximum visibility even under direct sunlight with the backlight off.
12) EXTERNAL POWER SUPPLY:
Powered by the vehicle’s 12V battery or an optional external battery. STEALTH-5 includes user-configurable power-saving and auto power-off functions to maximize battery performance. Supplied with an extension cable with eyelets for battery connection and a connector on the device side for quick disconnection.
13)WATER RESISTANT:
STEALTH-5 is water resistant and can therefore be used even in rainy conditions.
MAAT user interface allows the simultaneous management of various groups of graphs that can be created as desired and are included in "Container Windows" called Views.
It is therefore possible to populate the main view with the desired charts, for example those set to analyze the Engine parameters, and create a second view with the charts for the frame, etc.
By clicking on the vertical TABs on the left side of the screen, you can quickly switch between Views.
The Minimum, Average and Maximum table is a useful tool for identifying any peaks of sensor values or operating anomalies of the vehicle immediately after the data download.
Each column represents the maximum, average or minimum values (viewable by clicking the respective button) reached by the various sensors in the lap whose time is indicated in the column header.
MAAT highlights the peak value reached during the session with the color assigned to the sensor.
In the Comparison, the map gives the possibility to compare the trajectories to evaluate the most profitable ones.
The Laps Comparison is managed in MAAT as a new entity in its own right, with its own customizable Views and its charts.
At each lap loaded in comparison, a default color is assigned which represents all the channels and the trajectories related to that lap.
At the bottom of the screen, horizontally, the Delta graph is shown showing the progression of time deltas (if you are based on distance) and the distance delta (if you are on time basis).
