COVERAGE, SPEED, AND CAPACITY:

COMMStellation™ will be accessible to all terrestrial telecommunications networks across the globe. The MSCI COMMStellation™ will be comprised of 72 microsatellites on 6 orbital planes. Each orbital plane will contain 14 microsatellites including 2 additional microsatellite for redundancy.

How Does the COMMStellation™ Provide 100% Global Coverage?

COMMStellation™ is a polar constellation meaning that the microsatellites orbit the earth by passing over the north and south poles approximately along the lines of longitude. Positioned at 1,000 km above the surface of the earth, each microsatellite will cover a diameter of 4,819 km. If we draw a square within the diameter with corner points of the square touching the edge of the circle, this covers a square of 3,407 km on each side. The remaining rounded lobes between the edge of the square and the edge of the circle provide overlap between one microsatellite footprint and the next. Each orbital plane will be separated by 30° of longitude.

If the earth is sliced into 6 orbital planes, there are 12 spaces (between each plane). 12 spaces multiplied by each microsatellite footprint of 3,407 km equals 40,075.16 km, which covers the circumference of the earth at the equator (40,008 km). If the rounded lobes are brought back into the equation for signal overlap, the coverage completely blankets the earth. At the equator, the overlap alone covers an area of 1,480 km. Moving towards the poles, the overlap increases dramatically until multiple microsatellites are almost covering the same area. The coverage doubles at 60 degrees of latitude.

What is the Performance of COMMStellation™?

In comparison of a medium earth orbit (MEO) constellation comprised of 8 microsatellites at 8,000km above the earth to the COMMStellation™ low earth orbit (LEO) constellation comprised of 72 satellites, the following results are achieved.

A MEO constellation will orbit the earth at approximately 8,000 kilometers vs. COMMStellation™ which will orbit the earth at approximately 1,000 kilometers. Like the beam of a flashlight, the closer to the ground it is, the more concentrated the beam is and the less area it covers. With 72 satellites providing 100% global coverage, each COMMStellation™ satellite can concentrate its data bandwidth on a smaller ground footprint. With comparable individual satellite capability, the COMMStellation™ satellites can provide over 5 times the bandwidth to users for a given geographic area. In areas where bandwidth is limited, this will mean over 5 times the speed for an individual user.

The end result is that countries near the equator such as Ecuador, Columbia, Brazil, Gabon, Uganda, Somalia and Indonesia will get more than 5X the bandwidth (and speed) of a comparable MEO satellite. Moving north or south towards the poles, the amount of bandwidth data for a given geopgraphic area increase as the satellites converge (get closer to each other) enabling each satellite to focus its bandwidth on a smaller geographic area. An equatorial MEO constellation signal starts to weaken the further north and south a country is located from the equator. Markets such as the northern half of the United States, Canada, Europe, Northern China, and Russia get limited or no coverage at all by an equatorial MEO constellation but are fully covered by COMMStellation™ at 10x 15x the speed of a MEO constellation at its strongest point. COMMStellation™ is a minimum of 5X faster, with built in redundancy, a 99.9...% up-time, and 10x the capacity.
