Test of the gravitational redshift effect at Saturn

Recent astronomical tests of general relativity

“…Each of these stations was referenced to a hydrogen maser frequency standard. The result was in agreement with general relativity to 0.995 6 ± 0.000 4 as a formal uncertainty and ± 0.01 as a realistic uncertainty (Krisher et al, 1990).…”

Solar system constraints on Rindler acceleration

“…The result (23) connects directly the value of ξ with the Rindler acceleration a and allows, once the other quantities are known, to convert the limits on ξ into limits of a. This conversion is, unfortunately, not always possible due to the lack of information on these quantities in the literature.…”

“…At present there are many different measurements of the gravitational redshift which can be divided in two classes: the absolute redshift measurements and the null redshift experiments (see e.g. [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]). Both of these classes of experiments are based on a simple Newtonian derivation of the deviation of the gravitational redshift due to Haugan [29].…”

Solar and stellar system tests of the cosmological constant

“…From this uncertainty, we get a limit of Λ < ∼ 10 −23 km −2 . The gravitational redshift effect due to Saturn was tested with an accuracy of 1% from the Voyager 1 flyby [29]. Considering the spacecraft periapsis of 1.8 × 10…”
