Micro Stabilized FLIR Thermal and Visual UAV Payload M2-D
A micro gimbal for UAV and vehicle use that only weighs 160 grams is an amazing thing all by itself. But a micro gimbal that weighs 160 grams, has both a FLIR thermal camera and a visual camera with optical zoom and is gyro stabilized now that is something that you would call impossible. But its not. It is real. The unbelievable new M2-D micro stabilized gimbal features a 640×480 high resolution thermal camera with all the features (gain, level, polarity, color, digital zoom, etc). Co located is a very nice EO visual camera with OPTICAL zoom. Thats right this is not a kludge digital zoom but a true optical zoom down to 4.5 degrees FOV. Then of course there is a digital zoom kicker on top of that. Normally a 4 degree FOV in a UAV or ground vehicle will produce a very shaky unusable image. Thats why everyone fly’s with the consumer grade GoPro with its super wide angle lens. When using wide angle optics it is very easy to get smooth relatively shake free images but it is also very hard to get usable imagery and detail from any altitude. Try reading license plates with a GO PRO (maybe if your flying at 10′ AGL). The M2-D has advanced gyro stabilization just like the $1,000,000 FLIR balls that they fly on helicopters and military aircraft. This degree of stabilization is way beyond the consumer Chinese stuff you see on the web. With the Micro M2-D Gyro Stabilized EO/IR gimbal you can zoom in and read license plates from hundreds of feet AGL. This becomes a very useful tool for a wide range of applications. Ideal for a multitude of rotary and fixed wing uav’s, uas, ugv, multicopters, quadcopters, hexacopters. The unit is also compatible with DJI products.

The M2-D is built to the most exacting standards to withstand the harsh environment of UAV and Ground vehicle operation. There are also a host of accessories to make integration into any flying platform a breeze. There is a series of mounting options starting with a basic hard mount shock absorbing plate all the way up to a full blown retractable affair that can lift the payload completely up and into the body of the UAV when needed.

Control is also simple. There is a PC interface for bench use or integration into a larger software driven system. But, the most popular feature is the handy protocol converters. These tiny boxes can interface with any common Radio Control format. There is a PWM interface and a hot SBUS interface. Both easily integrate with auto pilot or manual controllers. They are both fully map-able via USB interface and included software.

Finally (as if this wasn’t enough), there is a geo reference tracking module that allows the unit to be directed to specific geo target locations and also return specific coordinates of any spot on the ground being viewed. This is real top end hardware and amazingly available in the ultra compact Micro Stabilized M2-D gimbal platform.

Its clear that the UAV imaging payload world has been stood on its head by SPI CORP. The M2-D is higher performance than any other system on the market. But that’s just the beginning of the story. The M2-D is about 1/4 the size of anything else on the market with these features and to seal the deal it is also a fraction of the price of anything ever made. The M2-D can also be custom installed onto military and industrial aerial vehicles such as aerostats, balloons, and a wide array of airborne, mobile, vehicle, marine and fixed platforms with radar, gps & remote sensing / tracking applications.

Background: Military unmanned vehicles UAV’s of today and tomorrow rely heavily on electro-optical EO Infrared IR sensor payloads to perform their missions.
These are the sensors that detect light in many different spectra, and enable unmanned vehicles to see. Electro-optical Infrared EOIR payloads are the sensors
that enable unmanned vehicles (UAV/UAS/DRONE) to see and avoid obstacles, detect movement, navigate accurately, find the enemy, and warn of the potential
for buried improvised explosive devices (IEDs). Designers of electro-optical Infrared Thermal EOIR – T sensor payloads for unmanned vehicles are under intense
pressure to evolve their technologies to keep pace with fast-moving trends in the unmanned vehicles industry. Perhaps in no other market are needs for ever-smaller,
lighter, and less expensive payloads as urgent as they are in the unmanned vehicles business. Small size, weight, and power consumption-known by its ubiquitous
acronym SWaP-is a paramount concern.
Unmanned systems, UAV’s Uas, Suas, Drones, Unmanned Robots, especially the airborne variety, are proliferating at an explosive rate, and demand is extending
beyond the military to more cost-sensitive industries such as law enforcement, agriculture, commercial remote sensing, traffic monitoring, and sporting events.
Put simply, a growing number of people need unmanned vehicles that are small, inexpensive, and reliable, and they need electro-optical sensor payloads to match.
Not only is there demand for ever-smaller, lighter, and less expensive electro-optical Infrared IR (thermal FLIR imaging, Thermal imaging IR Infrared Camera)
Gimbal Turret payloads, but demand for capability also is increasing.
As electro-optical and electronic component technology becomes smaller, lighter, and more affordable, payload designers sometimes have the option of choosing
between smaller size and weight, or more capability. Sometimes they strive to do both, and this presents some interesting possibilities in design tradeoffs.
Unmanned aerial vehicles (UAVs) are at the forefront of unmanned vehicle research, development, and procurement. Although no less important than
unmanned ground vehicles (UGVs) and unmanned marine vehicles, it is the UAV that is setting the agenda for unmanned electro-optical sensor payloads.
At the top of that UAV/UAS/Drone/Robot agenda is a broad trend toward large and growing numbers of relatively small UAVs that can provide local-area
and short-duration surveillance-the kinds of UAVs that can provide squad leaders a view over the next hill.
In the not-too-distant past there was a big push on developing sensor technology, and size and weight didn’t matter because DOD had large aircraft like
Global Hawk and Predator, as well as manned aircraft, hyperspectral imaging sensors are small and rugged enough to fit on relatively small UAVs.
Hyperspectral imaging is a sophisticated discipline that samples a wide variety of bandwidths in the light spectrum to provide a rich data set and detect
objects of interest not visible to single-bandwidth imaging sensors.
The key element to to reduce size and weight, that is Key!
Engineers started with a very small gimbal, and added high-definition visible-light video along with hyper spectral sensor payload.
The imperative for small size and light weight has forced mfg’s to a common material set able to withstand harsh environmental
conditions such as the stress placed on UAV takeoffs and landings. “The tarmac in the Middle East can be 120 degrees, and the payload must go to
thousands of feet a few minutes later where it is much colder,”
As electro-optical Infrared (Thermal imaging FLIR camera) Gimbal Turrets (EOIR FLIR) payloads for unmanned vehicles must continue to shrink in size,
the engineering challenges become heavier and force engineers to make some custom designs where years ago they would have considered only off-the-shelf solutions.
Many thermal cameras and shortwave infrared (SWIR) cameras available off the shelf are not made to withstand the physical rigors of small UAV, As a result,
Companies have been forced to evaluate the size of electro-mechanical elements of these sensors, and invest in new detector technology for electro-mechanical components
Custom design like this does not come cheaply, but electro-optical payload designers are seeking cost savings elsewhere.

The Evolution of Small lightweight affordable EOIR Thermal imaging Gimbal Turret Payloads incorporating
FLIR TV SWIR MWIR LWIR, CCD, BSTFA, Color Night vision, Cooled and Uncooled Infrared Technology will continue
To advance with the advent of smaller more efficient and sensitive detectors and lasers, The Gyro Stabilization will Get much better and smaller as well
