Introduction
JACIE 2018 | College Park, MD 2
• This presentation collects together geolocation accuracy performance assessments for the DigitalGlobe satellite constellation from imagery collected during 2017 and 2018 H1.
• The satellites have been performing well and provided good geolocation accuracy performance for 2017 and 2018 H1.
• CE90 and LE90 estimation is based on the Rank Order Percentile Method- Presented by NIQU/CCAP
