We report a microwave assisted optical vector magnetometer. Our method is based on the frequency difference and relative amplitudes of microwave-optical double resonances for different magnetic dipole transitions. Two hyperfine levels of $^{87}{\rm Rb}$ ground state are coupled strongly by a microwave field inside a cylindrical microwave cavity. A strong pump beam connects F = 2 [ground state] to F ′ = 2 [excited state], while a microwave field of frequency ω_μ pumps atoms between |1⟩ = |F = 1, m1⟩ and |2⟩ = |F = 2, m2⟩. The orientation of the microwave field with respect to the static field affects the amplitude of the double resonance peaks due to the polarization of the transitions, which provides us with information about the direction of the static field.
