We report on the measurement at 820 and 1400 MHz of the orbital modulation of the diffractive scintillation timescale from pulsar A in the double-pulsar system J0737-3039 using the Green Bank Telescope. With fits to this modulation, we determine the systemic velocity in the plane of the sky to be V_ISS≃140.9±6.2 km/s. The parallel and perpendicular components of this velocity with respect to the line of nodes of the pulsar's orbit are V_plane≃96.0±3.7 km/s and V_perp≃103.1±7.7 km/s, respectively. The large V_perp implies that pulsar B was born with a kick speed of ≳100 km/s. Future Very Long Baseline Array determinations of the angular proper motion in conjunction with improved V_ISSmeasurements should provide a precise distance to the system. Using high-precision timing data and the V_ISSmodel, we estimate a best-fit orbital inclination of i=88°.7±0°.9.
