The reusable, Swedish-made Saab Ericsson Aerospace S-19 guidance system for sounding rockets (see: https://www.google.com/search?q=Saa...chrome&ie=UTF-8 ), whose four delta steering fins make sounding rockets using it look like SAMs (Surface-to-Air Missiles), is useful for precision pointing for astronomical missions, and for greatly reducing the rockets' impact dispersion (a less-versatile solution, used on UK Skylark sounding rockets fired at Esrange and Woomera, is to spin the vehicle rapidly at launch; three Imp spin rocket motors spun up Skylarks, and Black Brant 12s use updated Hotseat spin rockets), and:

Spin rockets--or the S-19--enable high-performance sounding rockets to be flown safely at small-impact zone ranges, such as Esrange in Sweden (and at mobile ranges that geographically-isolated phenomena, such as solar eclipse ground paths, sometimes require vehicles to be fired not far from populated areas). A 1979 solar eclipse campaign in Canada made use of S-19 guidance system-equipped Nike- or Terrier-Black Brant VC vehicles, for that mobile range operation. The S-19 could also be used in a Speedball Nike-Apache-like, Black Brant simulated IRBM or ICBM target vehicle (the UK's Bristol Aerojet Petrel sounding rocket was also used as a simulated ballistic missile target, in Royal Navy service).
