For UNBabc mapping function, there are 11 mathematical operations to be carried out for getting the mapping function value. To ensure faster calculation, there is a need to simplify the mapping function models. The simplification of UNBabc mapping function model is using nonlinear curve fitting method. The UNBabc mapping function model for hydrostatics component is given in a form of continued fraction. This model has been selected to be simplified, due to its ability to achieve mapping function value, down to 2 degree of elevation angle. The comparison between the original models with the simplified models can be shown by calculating the sum of error. The number of mathematical operation can be reduced after the process of simplification of the model. The reducing percentage of original model to simplified model is up to 81 percent. © 2016 Author(s). date: 2016 publisher: American Institute of Physics Inc. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84984577779&doi=10.1063%2f1.4954572&partnerID=40&md5=ff45d599b231d9ca1e5e89776149f555 id_number: 10.1063/1.4954572 full_text_status: none publication: AIP Conference Proceedings volume: 1750 refereed: TRUE isbn: 9780735414075 issn: 0094243X citation: Batcha, S.R. and Sakidin, H. and Ahmad, A.
