BlackSky currently offers innovative geospatial solutions to customers, including optical data and analytics via its Spectra AI platform.

The addition of BlackSky’s advanced imagery and analytics products to our portfolio will place us in a stronger position to meet the varied business needs of our government and commercial customers in this region. More importantly, we see this as a first step towards a longer-term relationship where both parties can further leverage each other’s unique strengths and networks to develop novel, differentiated products and services to meet new user demands and expand into new markets,” said Goh Ing Nam, General Manager of ST Engineering Geo-Insights.
