Planet is now offering high-resolution SkySat imagery at 50-centimeter (cm) resolution with impressive revisit times. SkySat is a constellation of satellites continuously growing as Planet launches new ‘birds’ every year. Currently, the SkySat constellation revisits a site up to 3 times a day, and with upcoming launches this year that number will soar to up to 12 revisits a day, making it an ideal choice for high-resolution monitoring applications.
While previous SkySat satellites collected at lower resolutions, the vast majority of imagery collected from 2020 on can be delivered as a 50-cm 4-band pansharpened product. Further, all new and previously launched SkySat satellites (other than SkySat-1 and 2) now have a native resolution of 65-cm panchromatic and 81-cm 4-band multispectral (i.e. blue, green, red and near-infrared). Using an innovative system, Planet applies super-resolution processing to improve the quality of their high-resolution imagery to 50-cm.
Here is a summary of SkySat’s impressive specifications:
- Equatorial Crossing Time: 10:30 local time; 13:30 local time for only October 31, 2017 launched sats (approximate; across lit side of Earth); SkySats 16 – 21 crossing times vary daily, with a shifting ~3 hour access window per day
- Revisit Frequency: 3 to 12 times per day with the entire constellation (latitude dependent, pending additional 2020 launches)
- Sensor Resolution:
- Pre-2016 sats – 90-cm panchromatic & 1.0-m multispectral (at-nadir, 500 km altitude)
- 2016 to October 2019 – 72-cm panchromatic & 1.0-m multispectral (at-nadir, 500 km altitude); transition to 50-cm panchromatic started about October 2019
- July 2020 and on – 65-cm panchromatic & 81-cm multispectral (at-nadir, 500 km altitude); SkySats 1/2 remain at 72-cm panchromatic & 1.0-m multispectral; delivered as pansharpened 50-cm 4-band imagery through super-resolution processing
