Array Labs specializes in creating high-quality 3D imagery using a network of small satellites called radar cubesats. These satellites work together to capture images of the same area from different angles, resulting in 3D images that are significantly more detailed than other options available. The company serves various clients, including government agencies and urban planners, who need accurate imagery for tasks like mapping and disaster response. Array Labs operates on a subscription model, allowing clients to access its continuously updated imagery data. They also offer a pilot program for customers to help refine the product based on their needs. This approach enables Array Labs to provide timely and precise data, setting it apart from competitors in the geospatial imaging market. The goal of Array Labs is to enhance the geospatial imaging industry by offering cost-effective and high-resolution imagery solutions.
