Resilient communications
Voice, data and command relay that stays up when ground links are jammed or blocked by terrain.
HOVR · Stratospheric relay node
Connectivitythat holdsunder jamming.
HOVR is designed to restore communications, navigation and precise timing over contested ground: overhead within minutes of tasking, on station for hours, and owned by the nation that flies it.

The problem
Every force has sensors now. Under jamming, what fails first is the link, the position and the clock.
Denied
On a contested front, GPS and radio fail together.
Jamming and spoofing now cover whole theatres. Receivers lose their fix, radio networks lose the shared clock they synchronise on, and drones lose their link and their location at the same time.
Units trail kilometres of fibre-optic cable behind their drones to keep one link the enemy cannot jam. That is what a dependable link is worth.

Introducing HOVR
A persistent node at the edge of space.
HOVR holds station in the stratosphere and restores communications, navigation and timing across an entire area of operations, for every unit inside its footprint at once.

Signal geometry · illustrativeElevation, not power
Why it holds
Geometry the adversary can't outspend.
A jammer on the ground reaches a receiver from near the horizon, the direction an upward-looking antenna hears worst. HOVR transmits from almost directly overhead, the direction it hears best.
More jammer power raises the interference slowly. It does not change the angle the interference arrives from.

Link holding
Illustrative. Extra jammer power raises interference only slowly, because it still arrives from the horizon.
What it delivers
One overhead node. Four services that survive jamming.
Every user inside the footprint is served at once, from the same aircraft, with no masts to raise and no cable to lay.
Assured positioning
A position reference broadcast from a known point overhead, for forces and systems that have lost satellite navigation.
Precision timing
A low-rate timing signal that keeps radio networks, encryption and coordinated fires in step. It is the last service to fail.
Uncrewed systems
A jam-resistant control and navigation layer that keeps your own drones connected and located.
Operating concept
From order to coverage in minutes.
01
Deploy
Tasked by the unit that needs it and deployed on demand from behind friendly lines. No runway, no airfield.
02
Arrive
Takes up station over the area of operations within minutes of tasking.
03
Hold
Holds position for hours, serving every user in the footprint at once.
04
Recover
Returns, is recovered and turned around, and flies again.
Scale
One node holds an area. A network holds a front.
Add nodes to widen the area covered, and rotate them to keep coverage continuous. Each one is owned, tasked and flown by the nation that fields it.

Applications
Built for contested operations. Useful wherever networks fail.
Hover a row to move the globe
Contested land operations
Command, control and navigation for units under electronic attack.
Armed forcesUncrewed operations
Control links and positioning for drone fleets in jammed airspace.
Armed forcesMaritime and littoral
Overhead coverage at sea, where there is no terrain to mount a mast on.
NaviesDisaster response
Communications and position restored over a disaster zone within minutes of tasking.
Civil authoritiesCompany
We build the layer that keeps forces connected.
Parallel Aerosystems designs persistent stratospheric systems for communication, navigation and timing in contested environments. We work with defence ministries, armed forces and industry partners.
- Sovereign
- Owned and run by the nation that fields it. The system, its data and the decision to fly stay with the operator.
- Attritable
- Priced to be risked. Recovered to fly again.
- On demand
- Tasked by the unit that needs it, in minutes.
- Persistent
- Hours on station, holding position over the area of operations.
