Low Earth Orbit and Very Low Earth Orbit Satellites (e.g. Starlink)
A constellation of satellites that follow much lower orbits than geostationary or geosynchronous, but must complete an orbit many more times per day to keep from crashing to earth. This enables communication with satellites that are closer and through much less atmosphere. But it also means that the satellite you communicate with comes into view and leaves your dish's view, requiring a hand-off of communication and picking up a new satellite, over and over again. That makes the service dependent on a wide enough view of the sky to pick up a new satellite before losing contact with the current one. How wide that view must be is dependent upon how many satellites are up in which orbits that are visible from your location. Starlink satellites range from roughly 300 km to 500 km altitude, completing an orbit in roughly 90 to 95 minutes. The closeness also means there is far less latency (the time to send a packet to a satellite and for that to come back to earth elsewhere and be connected onto the internet and reach its destination. Up to the satellite and down adds roughly 2 (VLEO) to 6.6 milliseconds (LEO) to the packet latency from its other internet travels. [low latency] Starlink uses multiple radio bands (LEO satellites (500 km elevation) will transmit in the Ku (12- to 18-gigahertz) and Ka (26.5- to 40-GHz) bands, VLEO satellites (300 km elevation), will use frequencies up in the V band, between 40 and 75 GHz), some of which are absorbed by heavy rain or ice, but because of the fairly direct path through less atmosphere, this is much less of a problem than for geostationary satellite communications, however Starlink's statement on the subject includes this: "Heavy rain or wind can also affect your satellite internet connection, potentially leading to slower speeds or a rare outage." See starlink.com/faq for their complete statement and other things you should know as you consider starlink.
