What is Orbcomm satellite service?
ORBCOMM operates the world’s first and only commercial satellite network 100% dedicated to IoT and M2M, providing two-way data communications in the most remote areas of the world via a network of low-earth orbit (LEO) satellites and ground stations around the world.
What does Iridium communication do?
Iridium is a global satellite communications company, providing access to voice and data services anywhere on Earth. With its constellation of satellites, Iridium’s network connects people and devices in the world’s most remote places — and close to home.
What is Walker constellation?
A Walker constellation consists of a group of satellites (t) that are in circular orbits and have the same period and inclination. In addition to specifying the number of satellites in each plane, you must also specify the location of the first satellite in each plane relative to the first satellite in adjacent planes.
What is Ngso constellation?
Trending now: Non-Geosynchronous Orbit (NGSO) communications constellations. NGSO constellations include both Low-Earth-Orbit (LEO) and Medium-Earth-Orbit (MEO) satellites. For global coverage, these constellations require countless satellites and are somewhat more complex systems to operate and optimize.
What happened to ORBCOMM?
Orbcomm has entered into a definitive agreement to be acquired by private equity firm GI Partners, the company announced April 8. GI Partners made an all-cash transaction that values Orbcomm at approximately $1.1 billion including net debt.
What kind of company is ORBCOMM?
Orbcomm (stylized as ORBCOMM) is an American company that offers industrial Internet of things (IoT) and machine to machine (M2M) communications hardware, software and services designed to track, monitor, and control fixed and mobile assets in markets including transportation, heavy equipment, maritime, oil and gas.
Why is Iridium used in satellites?
Iridium NEXT also provides data link to other satellites in space, enabling command and control of other space assets regardless of the position of ground stations and gateways.
What do you call a group of satellites?
A satellite constellation is a group of artificial satellites working together as a system. Unlike a single satellite, a constellation can provide permanent global or near-global coverage, such that at any time everywhere on Earth at least one satellite is visible.
What is a mega constellation?
A Satellite Mega-Constellation is a group of man-made satellites operating together to cover a vast span of the globe or even the whole land mass. A network of satellites revolving on various orbits, a satellite mega-constellation involves satellites revolving on various orbits placed near to each other.
What is GSO and Ngso?
One of the main challenges in the coexistence of geostationary satellite orbit (GSO) and non-geostationary satellite orbit (NGSO) satellite networks is to mitigate the in-line interference caused by an NGSO satellite to the GSO earth terminal, while the NGSO satellite is crossing the GSO satellite’s illumination zone.
What is a LEO satellite?
Low earth orbit (LEO) is a designation for communication satellites whose locus extends from approximately 300 miles above the earth’s surface up to an altitude of 1,491 miles. A non-terrestrial network (NTN) of LEO satellites is called a constellation or swarm.
