Popis:	Simplified models relating pitch and roll angle measurements of a roving vehicle to terrain slope and vehicle attitude were developed. The simplified models are based on previously published models by Rowe and Spencer (1) and Yang et al. (2). These simplified models are easier to implement using microcontroller technology reducing the number of trigonometric function calculations, improving program execution and simplicity. Simulated and field tests were conducted comparing published and simplified models. In a simulated test, agreement between models showed coefficient of correlation (r) results of 0.999 (p
