SV01 is the first
GPS Block III satellite to be launched. Ordered in 2008 and originally intended to be launched in 2014, numerous technical delays pushed launch back to 2018. The spacecraft is built on the
Lockheed Martin A2100 satellite bus, and weighs in at 4,400kg (9,700lbs), making SV01 the heaviest GPS satellite ever launched. The satellite was given the nickname
Vespucci, after explorer and navigator
Amerigo Vespucci. == Launch ==
