The GRASP9 software is the most versatile tool available for analysing general reflector antennas and antenna farms. The package is a general tool to handle single, dual and multi-reflector configurations (beam waveguides). GRASP9 can calculate the electromagnetic radiation from systems consisting of multiple reflectors with several feeds and feed arrays. It is even possible to analyse the interaction between various antenna systems, a requirement which is often encountered in satellite systems where several antennas may be mounted in the vicinity of each other. The scattering from a feed or from a reflector of one system in a reflector of another system can thus easily be calculated. A vast amount of different surfaces, including user-defined shapes, can be analysed, just as the primary feed, or feed-array, can be selected from a substantial number of built-in models or from user-supplied data. Select in the left hand menu for further information about GRASP9.

GRASP9 is based on the heritage from GRASP8 which is used by all the major manufacturers as well as several service providers such as Eutelsat, Inmarsat and Intelsat. The software is the preferred tool for reflector antenna analysis in the space industry and has been developed and refined based on industry requirements and backed by the European Space Agency (ESA).
