摘要： An objective lens system includes a first lens group having a focal length F1 for focusing, a second lens group, which is a system of magnification variation having a focal length F2, a third lens group for compensation and having a focal length F3 and a fourth lens group having a focal length F4. The first lens group has a positive first lens assembly with a focal length F1a and a negative second lens assembly with a focal length F1b. The third lens group ensures an image point of the second lens group falls within the focal length F3 thereof. The first, second, third and fourth lens groups commonly form a finite conjugative system of magnification variation. Moreover, the objective lens system, as a whole, has a negative focal length.

摘要： The present invention provides a method for modulating a navigation signal, comprising: multiplying a data channel difference signal between upper and lower sidebands by a sine binary subcarrier to obtain an odd timeslot baseband signal of a branch Q, and multiplying a data channel sum signal of the upper and lower sidebands by a cosine binary subcarrier to obtain an odd timeslot baseband signal of a branch I of the data channel; multiplying a pilot channel difference signal between the upper and lower sidebands by the sine binary subcarrier to obtain an even timeslot baseband signal of the branch Q, and multiplying a pilot channel sum signal of the upper and lower sidebands by the cosine binary subcarrier to obtain an even timeslot baseband signal of the branch I; and performing QPSK modulation on the baseband signals of the branch I and branch Q to obtain a TD-AltBOC modulation signal. The present invention can implement transmission of different navigation services at two adjacent frequency bands, and each navigation service comprises a data channel and a pilot channel. The navigation signal of each sub-band may be received independently, or signals of the upper and lower sidebands may be jointly received to obtain high-precision navigation performance.
