In Colombia, the efforts of the government and NGOs to reduce their effects have succeeded in clearing minefields of more than 8 million square metres and destroying more than 7000 explosive devices. The standards for finding and clearing minefields (Confirmed Hazardous Areas CHAs) include the determination of geographical coordinates (Latitude and Longitude) based on DATUM WGS84. However, the precision or accuracy in the location of these coordinates according to their capture method has been little studied and analysed, so this research investigates three methods for capturing coordinates on a simulated minefield (CHAs), finding interesting results: (1) The static method with dual frequency GNSS receivers presented a standard deviation of 4 millimetres corroborating a high accuracy, by Stop and Go it ranged between 4 and 19 millimetres with respect to the mean showing also a high accuracy, control by simple radiation confirmed obtaining a mean positional difference of 4.62 centimetres, (2) the capture of coordinates obtained with navigator yielded a mean positional difference of 219.28 centimetres, very similar to that obtained with (3) azimuths and distances without correction for a magnetic declination of 235.73; However, when corrected for magnetic declination, it gave a positional mean with correction of 53. 32, which showed a reliability of the method as long as the declination correction is applied and starting from a point with sufficient coordinate accuracy. 2023 artículo científico 2145-549X https://www.redalyc.org/articulo.oa?id=517775572003 https://www.redalyc.org/journal/5177/517775572003/ https://www.redalyc.org/journal/5177/517775572003/html/ https://www.redalyc.org/journal/5177/517775572003/517775572003.epub https://www.redalyc.org/journal/5177/517775572003/movil https://doi.org/10.22335/rlct.v15i2.1742 en http://www.redalyc.org/revista.oa?id=5177 Revista Logos, Ciencia & Tecnología application/pdf Policía Nacional de Colombia Revista Logos, Ciencia & Tecnología (Colombia) Num.2 Vol.15 |
