Hi Gerhard,
I’ve researched the Spot product you saw at the last CES a few weeks ago. Spot is a product from the
satellite company Globalstar. Spot is for many years on the market and has seen some developments over years. The new innovative design and development is looking good and promising.
However, Spot relies on availability of the satellites from Globalstar. You can find a lot of posts on the availability of Globalstar’s Satellites for the voice system, the same will apply for the one way data system, Globalstar calls this their simplex solution.
The Globastar satellites are for many years in space and losing their strengths. Since last October Globastar is replacing their constellation (a set of satellites) with a new one.
To get a good overview of this new constellation at the moment, one need several sources to generate a story of the
current situation. Some of the sources are rumors, some is inside information. But at the end, quality of
service is crucial. With Globalstar, “QoS” is questionable. The BIG question with Globalstar is not when a message will be delivered but if it’s being delivered at all!
Besides the
delivery of messages, problems are also a question of coverage. The reason why you see a new (renewed)
introduction of an old system in place is that somehow Globalstar is focusing more on the
USA mainland because, big(ger) market or coverage is more reliable compared to for instance
Europe. If I’m looking at such a system, I’m not looking at one continent but a World Wide
service.
If you are thinking about Spot as a product you could use, I would think twice. It might be useless in a couple of month’s time and you might think your message is delivered where the message is
lost in space.
There are more reliable
satellite operators in space at the moment but more expensive as well.
The reason why I’m investigating messaging over satellite is for a special application and I will continue my
research, Globalstar will not be part of it.
I will keep you posted.
