SpaceX is preparing to launch its new fleet of Starlink laser Starlink satellites to provide wider Internet service coverage

SpaceX's Starlink Satellite Internet Service is preparing to launch its first batch of "laser" satellites, further expanding the global satellite Internet service area.

Starlink currently provides Internet broadband services to customers around the world through its network of small satellites, ground base stations and user terminals. To increase coverage, speed and cost, Starlink has also deployed new satellites featuring lasers to transmit data internally and expand the range of networks that operate independently of ground stations.

In that regard, Starlink just filed an application with the FCC to activate spacecraft in orbit.

The FCC commission accepted the application earlier this month. It requires regulators to approve temporary starlink satellite operations at latitudes above 53 degrees, because those areas are mostly remote parts of the planet where Internet connectivity is difficult to provide.

IT Home understands that Starlink uses satellites to transmit user data to a ground station, which then transmits the data to an Internet server center, which then passes the data back to the spacecraft to complete the cycle.

SpaceX already has dozens of ground stations across the United States, but it's much more difficult to build them in remote areas.

For these purposes, the company has focused on launching satellites with optical connectivity (or laser communication) to provide services to the polar regions. Elon Musk previously confirmed that all satellites launched this year would be equipped with lasers, and his company was only sending spacecraft to polar regions.

Starlink explains in the FCC's filing that the request is temporary in nature, as it will pass through its 10& DEG; Elevation runs, while Starlink is currently licensed at higher 25&DEg; Run at an elevation and say "run at a lower Angle" only Starlink is able to run at 25° "Stopgap measures" before services are provided.

The program requests a carefully limited temporary authorization to communicate only between the SpaceX satellite and the user terminal at an elevation of 10 degrees or more at the poles (that is, latitude higher than 53 degrees). This procedure does not seek authorization to deploy any additional satellites or earth stations. Nor does it seek any changes in the technical or operational characteristics of satellites and earth stations already authorized by the Committee, other than such small changes in the minimum elevation observed in polar regions. This stopgap measure will allow SpaceX to accelerate its high-speed deployment...

In simple terms, low angles help such micro-spacecraft communicate with user terminals, but can also cause problems such as poor communication due to long distances and terrain characteristics.

In addition, SpaceX has addressed some of the concerns of its friends because of the lower Angle. It assured the FCC commission. The elevation Angle of the OneWeb satellites will reduce interference to the OneWeb satellites as they are at 45& DEG; Or higher angles. It also plans to share data with the Kepler microstar system.
