Turyshev, Viktor T. Toth, 2009. _Space Science Reviews 148(1–4), 169–174_. A review by two of the Pioneer anomaly analysts. Gives the measured values (Galileo 1990 3.92 ± 0.08 mm/s; NEAR 13.46 ± 0.13; Cassini 2 ± 1; Rosetta 2005 1.80 ± 0.03; MESSENGER none), argues that incorrect modelling of reference frames and spheres of influence in navigation software must be excluded before new physics, and urges preservation of tracking and engineering data. **Earth flyby anomaly** Articledoi: **[10.1007/s11214-009-9571-0](https://doi.org/10.1007/s11214-009-9571-0)** Checked against the original0 ## What it's used for here The clearest statement of what must be checked and of the data-preservation problem. ## Cited by on this site 13 records [An error or inconsistency in trajectory modelling and navigation software (reference frames, spheres of…](https://mysteriesdept.com/mysteries/flyby-anomaly/answers/ANS0CWYEA7M1T1J/an-error-or-inconsistency-in-trajectory-modelling-and) Answer ANS [Only Earth flybys show it, because only Earth's field is known well enough or because the cause is specific…](https://mysteriesdept.com/mysteries/flyby-anomaly/answers/ANS0CWYEHST1R1E/only-earth-flybys-show-it-because-only-earths-field-is-known) Answer ANS [Two-way Doppler and ranging tracking of the Earth flybys](https://mysteriesdept.com/mysteries/flyby-anomaly/artifacts/ART0CWYEQ5P3MAF/two-way-doppler-and-ranging-tracking-of-the-earth-flybys) ART [Different teams with different software (JPL, ESA) found anomalies in different spacecraft.](https://mysteriesdept.com/mysteries/flyby-anomaly/evidence/EVD0CWYEAZ25DCE/different-teams-with-different-software-jpl-esa-found) Evidence EVD [Cassini passes at 1,175 km; about 2 mm/s found after thruster corrections](https://mysteriesdept.com/mysteries/flyby-anomaly/events/EVT0CWYE7HP02TB/cassini-passes-at-1-175-km-about-2-mm-s-found-after-thruster) EVT [Galileo passes Earth at 960 km and gains 3.92 mm/s unexplained](https://mysteriesdept.com/mysteries/flyby-anomaly/events/EVT0CWYE6T814YZ/galileo-passes-earth-at-960-km-and-gains-3-92-mm-s) EVT [MESSENGER passes at 2,347 km with no anomaly](https://mysteriesdept.com/mysteries/flyby-anomaly/events/EVT0CWYE81A6YBB/messenger-passes-at-2-347-km-with-no-anomaly) EVT [NEAR passes at 539 km with +13.46 mm/s](https://mysteriesdept.com/mysteries/flyby-anomaly/events/EVT0CWYE79W5WSH/near-passes-at-539-km-with-13-46-mm-s) EVT [Rosetta's first flyby at 1,956 km with +1.80 mm/s](https://mysteriesdept.com/mysteries/flyby-anomaly/events/EVT0CWYE7SG3SMJ/rosettas-first-flyby-at-1-956-km-with-1-80-mm-s) EVT [Slava G.
