Saab TransponderTech, a supplier of automatic identification systems (AISs) reports continued brisk sales of its AIS products, including shipboard transponders and base stations. Saab achieved two major milestones this year when it shipped its 10,000 shipboard AIS transponder and also installed the 1,000 shoreside AIS base station, according to Gunnar Mangs, vice president sales and marketing for Saab TransponderTech. Saab TransponderTech was one of the original pioneers in AIS technology and is currently offering its fourth-generation AIS products. The Saab R4, introduced in 2003, is the leading marine AIS transponder on the market. The product is type-approved to meet the IMO carriage requirements for AIS, and is fully licensed under the Swedish patent for AIS technology.
