The SkySat Advantage

Ideal for Monitoring
Planet’s monitoring product leverages the SkySat constellation for repeat collects of your high priority sites.

Multiple Images Per Day
As more SkySats are launched, this constellation will collect up to 12 images per day over a given location.

50-cm Panchromatic Video
SkySat can collect 50-cm panchromatic video over your area of interest.

81-cm Multispectral Bands
Unlike most high-resolution satellites, SkySat offers true 81-cm resolution, 4-band multispectral imagery without pansharpening.

Overview & HistorySkySat SpecificationsPricing

SkySat is a growing constellation of 21 (as of August 2020), sub-meter resolution micro-satellites. Launched in 2014, the satellites currently collect 65-centimeter (cm) panchromatic and 81-cm (m) 4-band multispectral (i.e. blue, green, red and near-infrared [NIR]) imagery – which is delivered as 50-cm 4-band pansharpened imagery through super-resolution processing. Originally built and launched by Terra Bella, the first seven SkySat satellites were acquired by Planet in 2017. Since then, Planet has added a number of microsats to the constellation.

SkySat’s impressive flock of microsats is ideal for monitoring high-value sights offering up to 12 revisits per day over a given location with the additional capability to capture 120 seconds of 50-cm panchromatic video. Micro-satellites are small with shorter life expectancies then their larger counterparts like WorldView-3, so expect to see more SkySats launched into orbit as the original microsats reach the end of their lifespans.

Imaging System
  • Spectral Bands:
    • Panchromatic
    • 4-band multispectral (blue, green, red and NIR)
