Factory Capabilities

What Is a Handheld Laser Target Locator?

A product is an advanced electro-optical instrument that combines precision laser ranging, digital compass, GNSS positioning and optical observation in a portable form factor. The device calculates the exact geographic coordinates of remote objects by integrating laser time-of-flight measurement, magnetic azimuth detection and satellite-derived self-position data.

For artillery observers and forward reconnaissance teams, the system solves the targeting gap—the critical delay between visual identification and coordinate extraction. By automating spherical trigonometry and eliminating manual map work, it reduces human error in high-stress environments and shortens fire-mission timelines from minutes to seconds.

Professional systems like the MHNV MH-OL25 employ Class 1 eye-safe 1535 nm lasers. This wavelength is invisible to both naked eyes and night vision devices, ensuring operator stealth while eliminating ocular hazard zones that restrict shorter-wavelength 905 nm devices.

Four-Target-Class Ranging Envelope for Real-Mission Planning

The MH-OL25 publishes distinct maximum-range figures for each target class instead of one ambiguous "up to" number.

Target Class	Maximum Range	Typical Application
Building	≥25 km	Coastal watch, urban observation
Vehicle	≥17 km	Road surveillance, convoy tracking
Personnel	≥8.5 km	Border security, infiltration detection
UAV	≥6 km	Airspace monitoring, drone interdiction

This four-class envelope lets operators predict actual mission range for the target at hand. Coastal watch teams tracking shipping at 20+ km, artillery observers correcting fires at 15+ km and border surveillance detecting personnel at 8+ km all benefit from transparent performance data. Combined with ±5 m accuracy and 1 to 5 Hz measurement rate, the product supports both single-shot stealth ranging and continuous tracking of moving vehicles, boats and aircraft.

Sub-Mil Grid Precision for First-Round Artillery Correction

The MH-OL25 integrates a sub-mil electronic compass with 0.3° azimuth accuracy, 0.1° pitch and roll accuracy, ≤3 m self-positioning accuracy and ≤1 mil target positioning accuracy. This combination delivers grid coordinates that meet indirect fire control standards.

Artillery observers forward 10-digit grids that place the first correction round inside the target area. Drone strike coordinators export PLI (Position Location Information) directly into Android Tactical Assault Kit or battle-management systems. Coastal watch teams hand off real-time coordinates to patrol vessels. The device eliminates manual map protractors, reduces transcription errors and cuts fire-mission delays from minutes to seconds.

Multi-target relative distance measurement mode stores waypoints for sequential target handoff. Map positioning correction compensates for local magnetic variation. Ballistic calculator support allows custom target-class data entry, so one procurement contract serves artillery observation, border surveillance and coastal watch missions from the same device.

Direct-View Optics with Dead-Battery Ranging Capability

The MH-OL25 employs direct-view optics: real photons pass through the 42 mm objective and reach the observer's eye with zero processing latency. The 7× magnification with 6.7° field of view offers the brightness and situational awareness required for wide-area scanning. −5D to +5D diopter adjustment covers the full range of observer eyesight without corrective eyewear—critical when arctic conditions cause eyeglasses to fog inside the eyecup.

The reticle-based rough ranging remains functional even when electronics fail. If the battery drains during a multi-day observation post, the operator can still estimate range using the mil-dot reticle and maintain mission continuity. Fully-digital locators lose all capability the moment power is lost. This backup ranging architecture is a decisive advantage for extended reconnaissance missions.

RS232 Full Data Transmission and Command-Post Integration

The MH-OL25 broadcasts real-time compass data, range, GPS coordinates, target grid, ballistic solutions and target-class metadata over RS232 to command laptops, drone ground stations and war management systems. Scalable digital image output supports an optional camera add-on for evidence capture and video handoff to remote command stations.

Systems that only provide a manual range readout require the operator to voice-call every observation, introducing transcription error and multi-minute delays to every fire-mission request. The RS232 interface removes voice loop bottlenecks and adds the Handheld Laser Target Locator to network orientated activities. You can automate target logging, construct a persistent common operating picture and give off coordinates to many fire assets off a single observation.

Rugged IP67 Design for Arctic, Desert and Coastal Deployment

The MH-OL25 works from −40 °C to +60 °C, covering arctic frost, desert heat and coastal humidity. IP67 sealing against entrance of dust and immersion up to 1 metre for 30 minutes. The 2.5 kg weight allows the device to be considered as a sturdy target-locator while still being portable enough for true handheld use. Operators can carry and use the system for long periods of time without tiredness.

Internal power supply works continuously not less than 7 hours. Multi-day observation posts are available with rechargeable battery packs for swapping in the field. Rugged housing to withstand shock, vibration and rough handling typical of forward deployed activities ensures mission ready performance in the hardest conditions.

FAQ

Q: Is the 1535 nm laser safe for human eyes and friendly troops?

A: Yes, the MHNV MH-OL25 employs a Class 1 eye-safe laser at 1535 nm, which is invisible to both the naked eye and night vision devices and poses no ocular hazard at any distance. Unlike shorter-wavelength 905 nm devices that require restricted firing corridors and exclusion zones, the 1535 nm architecture allows you to range targets in mixed environments with friendly troops, civilian bystanders and reflective surfaces present, ensuring operational safety and signature discipline without compromising range performance.

Q: How does atmospheric weather affect the product?

A: While heavy fog, rain and snow can scatter laser pulses and reduce effective range, the MH-OL25 uses multi-pulse logic and advanced signal processing to filter atmospheric noise and prioritize the last solid return. High-end 1535 nm lasers penetrate haze more effectively than visible-wavelength systems, and the 1 to 5 Hz measurement rate allows you to capture valid returns during brief atmospheric clearings, maintaining mission capability in adverse weather that would ground purely optical systems.

Q: Can the device work without GPS or in GNSS-denied environments?

A: Yes, when GNSS signals are jammed or unavailable, the product can calculate relative target positions using known reference points, the internal digital magnetic compass and manual position entry. You can establish a local coordinate grid from a surveyed observation post and derive target locations through azimuth, elevation and range data alone, ensuring fire-mission continuity even in electronic-warfare environments where satellite navigation is degraded or denied.

Q: How often does the electronic compass need calibration?

A: To maintain sub-0.3° azimuth accuracy and ≤1 mil target positioning precision, field calibration is recommended whenever you move to a significantly different geographic magnetic zone, after exposure to strong electromagnetic interference or near large ferrous objects. The MH-OL25 includes a rapid field calibration routine that completes in under two minutes, allowing you to restore full precision without returning to a workshop or interrupting extended observation missions in forward-deployed locations.

Q: Does the MHNV MH-OL25 integrate with Android Tactical Assault Kit (ATAK) and C4I software?

A: Yes, the RS232 full data transmission interface and scalable digital output are specifically designed to export Position Location Information (PLI) and range data into ATAK, Windows-based command-and-control systems, drone ground stations and battle-management networks. The open protocol allows you to stream real-time target grids, build a persistent common operating picture and hand off coordinates to multiple fire assets without voice-loop delays or manual transcription, significantly shortening the sensor-to-shooter timeline for time-sensitive targets.
