A ground station, earth station, or earth terminal is a terrestrial radio station designed for extraplanetary telecommunication with spacecraft, or reception of radio waves from an astronomical radio source. Ground stations are located either on the surface of the Earth or in its atmosphere. Earth stations communicate with spacecraft by transmitting and receiving radio waves in the super high frequency or extremely high frequency bands (e.g., microwaves). When a ground station successfully transmits radio waves to a spacecraft (or vice versa), it establishes a telecommunications link. A principal telecommunications device of the ground station is the parabolic antenna.
Why would I pay for a satellite tracking service when AIS can do it for free?
A quick warm up to AIS and comparative notes below. There are specific technologies that are built for specific purposes and they are GREAT at providing the intended service for the intended solution. AIS is a good global generalized picture of assets in the loosest terms possible because it’s not what it was built for. We will get into details how/why/what below.... More
Iridium Push To Talk (PTT) is a newly commercialized service that is extremely useful for the market, but is also not well understood so lets learn a bit about how it all works.
To start with, Iridium PTT is not a "Nextel" style of phone where you simply push the "key" button and broadcast a message to your group and then go back to normal telephone calls and SMS. The Iridium PTT phone must be booted into one of two modes when it is powered on,... More
You might be surprised at the how differently satellite and GSM terminals operate to remain competitive on airtime. There are applications where the airtime costs are identical to GSM solutions, which are regarded as the lowest cost solution in the industry. Hardware pricing is still more expensive than GSM solutions simply based on the complexity, volume of terminals, and transmission distance and power to the satellite. This does have an... More
There is little education outside of a small group of people in the satcoms industry about the various satellite networks. One of the first things is understanding what the major differences and benefits are of each network. Here we will run over the various technologies and come to a few conclusions based on your needs to select the best network. There are many networks available but the most popular in my industry are Inmarsat, Iridium,... More
GSE was born from an aviation project, PlaneSight, that transmitted encrypted video over satellite. A task that many said could not be done; we designed, tested, and deployed a solution within six months using a bank of 16 satellite modems with custom firmware and a new multilink protocol designed in house.
