The Global Differential GPS (GDGPS) System is a real-time GNSS monitoring and augmentation system that provides location information to about 3-inch position accuracy. They use a large ground network of real-time reference receivers, innovative network architecture, and real-time data processing software, the GDGPS System provides sub-decimeter (less than 10 cm) positioning accuracy and sub-nanosecond time …
SpaceX has a new FCC filing to adjust the orbital deployment of Starlink satellites to accelerate deployment of commercial service. SpaceX plans to provide continual coverage over northern states after as few as six more launches. They need license modification to speed up deployment in the Southern US. SpaceX’s filing stresses the importance of quickly …
SpaceX is planning four Starlink satellite launches by the end of 2019. This would put 240 satellites into orbit. The four launches are currently targeting: October 10 October 25 November 13 December 8 SpaceX can provide service top the USA and Canada after 360 satellites are operating in orbit. Previously SpaceX had talked about two …
The image tweeted by Trump was at about 10-centimeter resolution. It was likely a picture taken by the US224 satellite. This was one of the upgraded keyhole satellites that have the same mirror as the Hubble Telescope (2.4 meters). It was widely known for many years that the Keyhole spy satellites were using the same …
Most of the fires in Brazil were likely set by farmers preparing the land for next year’s planting. This is common farming method said the scientists from the University of Maryland. The fires are burning on agricultural land where the forest had already been cleared. Brazil’s National Institute of Space Research calculated that there were …
Facebook, OpenStreetMap, and Map with AI are creating tools that will enable vastly faster mapping of unmapped roads and other unmapped feature. Artificial intelligence to predict features on high-resolution satellite imagery; these features are then populated in our RapiD map editing tool. When combined with global-scale humanitarian efforts, they hope RapiD can help realize our …
Capella Space constellation of small but powerful satellites employ space-based radar, beaming through darkness and cloud cover to gather the information you need to make informed decisions. When fully deployed, Capella will offer hourly coverage of every point on Earth, rendered in sub-meter resolution, through the world’s largest constellation of radar satellites. Capella micro-satellites are …
Mark Handley (UCL, University College London) has simulation showing the orbits of various SpaceX Starlink satellite constellations. There are simulations of 72, 264 and 11927 satellites. SpaceX is launching 60 satellites at a time. SpaceX has 60 production Starlink satellites in orbit now for testing.
SpaceX has raised over $1 billion and this will be enough money to make and deploy the 720 Starlink satellites that are needed for an operational constellation. Musk said SpaceX will have most of the space launch revenue at $3 billion a year. SpaceX already has 60% of commercial launch. Elon believes internet service revenue …
SpaceX is scheduled to launch launched the sixty Starlink satellites in 2.5 hours at 10:30 EDT – 7:30 PDT time. The launch is successful and they landed the first stage. The second burn will start in about six minutes to get to the right orbit. Second stage engine cutoff confirmed, now in coast phase. The …
Elon Musk tweeted that only six launches of Starlink Satellites will be needed to reach initial activation of a 360 satellite constellation. 720 satellites from 12 launches will provide significant coverage of the US and Europe. 360 satellites would only provide minor coverage.
