Definitions
- the present invention relates to antennas for scrolling satellites.
- the antennas used by scrolling satellites are either type antennas omnidirectional (SPOT, ERS, etc.) or directive pointable (LANDSAT, etc).
- the beam is Gaussian and scanning is carried out using a pointing, the antenna behaving like a Classic design centered parabolic reflector.
- Document US 5,587,719 describes an assembly of antennas for satellite to communication comprising several aligned elementary helical antennas along their longitudinal axis.
- Each elementary antenna includes four strands regularly distributed in a helix around a cylindrical generator.
- antennas having a winding of their strands in one direction given are inserted between antennas with a winding in direction opposite.
- An object of the invention is to propose a antenna for traveling satellite which does not require no pointing mechanism, which has a gain superior to omni-directional antennas and that is space-saving and low cost.
- the invention proposes a system according to claim 1.
- the beam emission beam is an elliptical beam ("fan beans” according to Anglo-Saxon terminology) which extends in a direction parallel to that of the vector satellite speed.
- the antenna illustrated in Figure 1 has a plurality of elementary radiating elements referenced by 1.
- These elementary radiating elements 1 each have a plurality of helical strands regularly distributed around the same generator revolution.
- the generator is for example conical or cylindrical. These strands are supplied in an equi-amplitude manner.
- these strands there are four of these strands and define four identical propellers, offset by ⁇ / 2 relative to each other. These four strands are advantageously supplied with phase quadrature.
- the angular radiation pattern of such elementary radiant element is of the type illustrated in figure 2.
- This diagram corresponds to the diagram obtained for an axial height of the radiating element of 0.050 m, a basic radius of 0.018 m, as well as a frequency 8000 MHz transmission. It is related to a sphere of measures 10 m in diameter.
- the elementary radiating elements 1 are distributed in line in a plane perpendicular to the direction of the velocity vector.
- the pitch between said radiating elements 1 is by example of 19 mm for an emission frequency of 8000 MHz, which eliminates the need for network lobes.
- the pitch d of the network is such that d ⁇ / (1 + sin ⁇ ) where ⁇ is the wavelength of the radiation, and ⁇ the maximum depointing desired.
- the radiating elements 1 are supplied via phase shifters 2 of ferrite type and couplers 3, by a power distributor 6 (in this case 1: 5), which is for example of the waveguide type.
- phase shifters 2 are controlled by a unit 4, which is the satellite on-board computer, to which they are linked by control electronics 5.
- phase shifts imposed on the different elements 1 radiators are used to make the depointings desired, up to ⁇ 62 °.
- the choice for radiating elements 1 of propeller structure provides a gain at 50 ° 2 dB higher than the gain presented at 0 ° (excluding the space attenuation difference compensation -62 ° satellite lift from the zenith) and therefore naturally compensate for the loss of depointing.
- the optimal number of radiating element elementary will vary from five to twelve depending on mission needs.
- the phase shifters 2 for example have steps of 22.5 ° quantization and are coded on 4 bits.
- the beams generated by such an antenna are elliptical (major axis of ellipses parallel to the trace satellite).
- the cover is shown obtained in the case of phase shifts respectively of a radiating element from one end to the other at 90 °, 45 °, 0 °, - 45 ° and -90 °.
- the diagram is then deviated by + 18 °.
- the directivity is 11.52 dB.
- the depointing is then 32 °, the directivity 11.49 dB.
- the depointing obtained is 48 °, the directivity 11.45 dB maximum.
- the directivity obtained at 65 ° is greater than 9-dB, or a gain greater than 7.5 dB if we consider losses of 0.5 dB on the distributors, of 0.5 dB for phase shifters, 0.25 dB at the connection and 0.25 dB at the power supply.
- the depointing antenna which has just been described allows high ground retransmission rates and allows retransmissions of High resolution images.
- Beam switching takes place preferably before passage, so as to avoid phase jump problems on the generated coverage.
- the depointing antenna which has just been described has the advantage of being low cost and above all small footprint.
- the size of the part radiant is 90mm in length, 5mm in width and 50 mm in height.
- the antenna comprises several online antennas of the type which has just been describes and switching means for switch from one online antenna to another depending movements of the satellite, and in particular of its roll movements.
- the antenna includes means for motorization which allow to modify the orientation of the line (s) of elementary radiating elements to compensate for potential movements of the satellite, especially its rolling movements.
