| Abstract: | The results of simulation and ground measurements show that there is obvious non linenar variation in vertical gradient of gravity from the ground surface to a height of 80 cm and 130 cm，the amount is more than 002×10-8ms-2/cm，and the variation of gradient increscent with the changes of elevation.Therefore，the difference caused by height has to be paid attention in gravity measuring with FG5 and A10 absolute gravitymeter |
| Keywords: | sidehill gravity absolute gravimetry vertical gradient of gravity non-linear |
