Performance

Pegasus utilizes an innovative hybrid propulsion system designed for power, efficiency, and reliability.  It provides the power to fly high above weather and air traffic, overcome stratospheric winds, and operate anywhere in the world - Pegasus can fly more than halfway around the Earth non-stop.

Up to 8 days endurance

13,000 mi range

70,000 ft altitude

146 kt speed

Flight at all latitudes

Operations

Pegasus is fully autonomous from startup to shutdown with human oversight as necessary.  This combined with a robust airframe enables operations and maintenance similar to general aviation aircraft.

Conventional takeoff and landing

350 ft takeoff distance

30 kt headwind, 15 kt x-wind takeoff limits

Storage and transport in a 40 ft container

Built to meet FAA and ASTM standards

Payloads

Generous payload bays in the nose cone, tail cone, and fuselage for our sophisticated telecom equipment, cameras, sensors, data servers, or any system that fits

165 lbm capacity

5 kW continuous power

70 cu ft volume

MERCURY

Engineered internally, our high-bandwidth, low-latency wireless backhaul creates seamless air-to-air and air-to-ground data links.

Leveraging cutting-edge pointing and tracking software, paired with a precision-controlled gimbal, we establish long-range point-to-point connections hundreds of miles away.

<0.1° pointing accuracy

Up to 500 mi air-to-air range

40 Gbps bandwidth

40 ns latency plus time of flight

E-band

HERMES

A state-of-the-art aerial 5G antenna, Hermes connects directly with user devices to provide mobile internet service.  Our active phased array antenna utilizes available spectrum efficiently and prevents interference with terrestrial cell towers.

Active phased array

Frequency Reuse 1

Bandwidth up to 100 Mbps

Mid-band 5G frequency

Time division duplex (TDD)

FLIGHT IS THE FUTURE OF CONNECTIVITY

Zenith is bringing together proven technologies at the perfect time to revolutionize connectivity.

Boeing Condor proved autonomous, multi-day, stratospheric flight using piston engines in the late 1980s.

Angel Technologies demonstrated airborne telecommunications from the high-altitude Proteus aircraft in the late 1990s.

Now, Zenith is shaping the future of connectivity with innovations in propulsion, manufacturing, and flight software technologies.

AIRBORNE TELECOM IS FASTER THAN SATCOM

​Satellites are too far away from users to provide high-bandwidth and low-latency service directly to mobile devices.

LEO satcom requires large, monolithic constellations of expensive satellites - driving up costs and creating a rigid, centralized, one-size-fits-all network.

HYBRID PROPULSION CAN REACH EVERYONE

Solar aircraft are limited to operating within about ±35° latitude in order to collect enough solar energy to recharge their batteries, excluding Europe, half of North America, half of Japan, and more.

Zenith’s technology provides global coverage and reliable performance, overcoming these constraints for uninterrupted service.​
