Sky Sapience Introduces HoverMast – a Lightweight Autonomous Hovering Platform

The ‘HoverMast’ developed by the Israeli start-up company Sky Sapience is scheduled to go on an operational demonstration in the upcoming months, demonstrating the system’s capability to expand the surveillance coverage of unmanned ground vehicles. The payload currently integrated on the HoverMast is the T-Stamp from Controp, a stabilized multi-sensor payload. The HoverMast will be unveiled at the upcoming AUVSI Conference and Exhibition to be held in Tel-Aviv next month.

Sky Sapience developed HoverMast in the past two years, in response to an Israel Ministry of Defense (MOD) requirement for a lightweight tethered hovering platform. The system was one of several concepts evaluated by the MOD Research and Development Directorate (DDRD), which eventually selected the HoverMast for the sole developer of the tethered platform technology. Under the partnership with DRDD Sky Sapience developed the platform and conducted a series of prototype flight tests. HoverMast is positioned as an effective platform for military surveillance, observation and target acquisition applications, as well as deployment of communications gear, communications intelligence (COMINT) and other electronic devices. It will also offer an affordable application for border surveillance, urban security, crowd control and other civil applications.

According to Brig. General (IAF Ret.) Gabriel Shachor, CEO and Founder of Sky Sapience the HoverMast was developed specifically for small vehicles such as the Guardium-LS from G-Nius, the vehicle selected for integration with the HoverMast. Other applications include the Zibar light reconnaissance vehicle. According to Shachor, the platform is due to enter production toward the autumn this year. Sky Sapience has strategic partnerships with DRDD (MAFAT) – the IMOD research and development agency and G-NIUS Unmanned Ground Systems Ltd.

Shachor claims the HoverMast favorably compares to the 7-5m’ telescopic masts currently mounted on surveillance vehicles, offering faster response, lighter weight, and the capability to operate on the move. Furthermore, the new platform alleviates the need to operate from a horizontal surface and is less sensitive to wind gusts. According to Shachor, the HoverMast would also be more affordable than mast mounted systems.

The deployment is fully automatic, with HoverMast deploying from the stowed position to an elevation of 30-50 meters in just 15 seconds. A cable that also provides power supply and wide-band data link tethers the vehicle. The platform uses a coaxial counter-rotating ducted fan for lift generation, with four thrusters providing station keeping, maneuvering and stabilization. At a 10kg net platform weight HoverMast can carry up to 9 kg of payload, comprising electro-optic sensors, laser designators, radar, or signals intelligence sensors. Sensor data can be transmitted to remote clients or fed through the tether datalink to the base station.

In the stowed position the HoverMast automatically folds into a compact 72 cm diameter container, carried on a vehicle flatbed or roof, mounted on UGVs or All Terrain Vehicles (ATV), or small naval craft; making the system especially suited for Special Forces, border and port protection, and infantry missions.




  1. How does this new platform compares with the ETOP, recently developed by the IAI ?? IAI’s ETOP brings up a 20 kg load up to 100 meters. This new, less expensve, smaller and lighter platform takes 9 kg up to 50 meters. Do you know, whether these two systems are going to “complete” each other, i.e. to exist paralell – or, is it so, that this new, smaller system is going to replace the IAI’s solution ??

      • However, Joe, even IAI’s ETOP is small enough, and light enough, as to be quite easily used on vehicles (and even on not so big ones, like for instance ZIBAR Mk 2), as well as on naval crafts, like Dvora or Shaldak. It takes the double load, and goes twice as high. Perhaps the price is the factor, regarding which one should be used for some specific task or application.

  2. Well, this seems pretty basic, using prop powered technology for hovercraft. Raytheon (along with the US and probably most world powers) has actual “flying saucer” technology, assumingly used for surveillance. I know two people who actually saw one fly above them! It was about a foot in diameter. They then told a friend who used to work at Raytheon, and he laughed and said he knew about that technology. But I guess the military kinda want to keep their best secrets secret. A good book on the issue of US/UK Saucer technology is “Hitlers Flying Saucers: A Guide to German Flying Disks of the Second World War.” The author basically goes on a hunt to discover the UFO issue. And once complete, puts to rest all the wild speculations of extraterrestrials–and ultimately the truth is much more down to earth, lol.

  3. This type of multicopters was invented in Lithuania. Application number LT2012007.
    Quote: The invention makes it possible to increase the load capacity and improve the
    manageability of light helicopters with six or more carrying rotors. The effect is achieved by
    using different rotors to create a thrust and to carry out maneuvers. The average speed of the
    rotors’ rotation, providing maneuverability, does not decrease during flight. The diameter and
    mass of the rotors providing maneuverability is restricted in order to decrease the inertia. The
    invention is applicable for light flying devices where it makes economic sense to use rotors with
    a fixed pitch angle.
