Studies on atmospheric density were very important to obtain a correction factor for the atmospheric density model. Thus, improvement of atmospheric models accuracy, i.e. CIRA, JASCHIA, NRLMSISE, became important in its application for re-entry prediction, satellite tracking and mitigation of the collisions probability between active satellites with space debris. GPS equipment installed in LAPAN-A2 indirectly measured the upper atmospheric density variation in-situ from the satellite orbit path. Notwithstanding the measurement had a lower temporal resolution than using accelerometer, but still gives better resolution than using Two-Line Element (TLE) data. This study had successfully determined upper atmospheric density variation with a 10 second resolution using LAPAN-A2 GPS data. The LAPAN-A2 GPS data validated using In-track Radial Cross-track (RIC) had ± 2 km error compared to the TLE data. It was also found that there was influence of solar activity on atmospheric density changes obtained from the LAPAN-A2 GPS data
