The STREAM product line consists of a series of versatile low-cost Iridium transceiver packages that enable end-users with two-way connectivity over the Iridium® Satellite Network anywhere on the planet. STREAM+ simplifies data access by transferring user data to an Amazon Web Service (AWS) file management service. Designed for field applications with size, weight, and power constraints. The STREAM+ offers a range of industry-standard protocols, features, and inputs enabling end users with flexible integration and installation options. This versatility reduces development costs and overall time to market. Powered by the Iridium Certus® 100 midband service, the STREAM+ allows users to send and receive files and messages reaching a few megabytes securely, removing the need to worry about intermittent connectivity disruptions.
