of Cartosat-2D separation) Inclination: 97.46° Period: 94.72 minutes Launch azimuth: 140° The rocket launched Cartosat-2D and 103 nanosatellites: two from India, one each from Kazakhstan, Israel, the Netherlands, Switzerland, and the United Arab Emirates, along with 96 from the United States – 88 Dove satellites and 8 LEMUR satellites. The three Indian satellites launched were Cartosat-2D, INS-1A, and INS-1B. Arrangements for the launch of the 104 satellites were made between ISRO's commercial arm Antrix Corporation Limited, under the auspices of the Indian Government's Department of Space, and the international customers. The Cartosat-2D weighs , and its design life is five years. The two Indian nanosatellites, designated INS-1A and INS-1B, each carried two payloads from ISRO's Space Applications Centre and the Laboratory for Electro-Optics Systems. INS-1A carried a Surface Bidirectional Reflectance Distribution Function Radiometer (SBR) and a Single Event Upset Monitor (SEUM). INS-1B carried an Earth Exosphere Lyman-Alpha Analyzer (EELA) and Origami Camera as payloads. They weigh and respectively and have been designed with a mission life of six months. An ISRO official said: "The nano satellites are an experimental class of satellites introduced by ISRO because there are requests from academic institutions to use them for data collection. The universities do not have the knowledge to build satellites and tend to take a long time… We want them to focus on the instruments as we can provide the nano satellite bus." The 103 co-passenger satellites weighed approximately , bringing the total payload mass to . The total launch mass of the rocket was . Among the 96 satellites belonging to US companies, 88 CubeSats were owned by Planet Labs, a private Earth imaging company based in San Francisco, California. Weighing roughly each, the satellites separated from the rocket in different directions to avoid collision. With the launch of PSLV-C37, Planet Labs increased its fleet of satellites to 143, which is the largest private satellite fleet in operation. Eight Lemur-2 satellites belonging to Spire Global are to provide vessel tracking and weather measurement services. These satellites have a short lifetime of about two to three years requiring replacement at regular intervals. PSLV-C37 used the rocket engine nozzle manufactured by Vijayawada, from Andhra Pradesh-based company Resins and Allied Productions (RAP). This is the 100th nozzle manufactured by RAP to be used in a PSLV. Several components of PSLV-C37 were manufactured by Larsen & Toubro at its advanced composite facility in Vadodara, Gujarat.
