Four times GNSS

摘要

The Munich Satellite Navigation Summit opened during the first week in March 2009 with a plenary session entitled 'The Worldwide Race in GNSS' and closed with a panel discussion on the subject of 'competition among the Big Four'. Although several speakers did their best to convince attendees that there was no race or competition, it is obvious that four systems serving the same market will be involved in a race for the best technical solutions and engage in fierce competition. If it is indeed a race/ competition, let us have a look at the score so far.
