USE AT DRAO (Radio Astronomy and Riometry).
See Note RA.0

The DRAO site is intended to be one of the primary passive sensing sites in the Canadian Geospace Monitoring Program (CGSMP). However, the only band allocation relevant to this program is probably this one.

5.149 ~RA in 25 550-25 670 kHz

There is a proposal to build a radio telescope on this site that would use this band. However at this point it is a proposal and not yet funded.

CSA: project called SCISAT (science satellite) will be using 2223-2237 MHz (s-E) and 2050 – 2057 MHz (E-s)

Bell: has applied to the Regional Office to use part of the paired spectrum (2200-2285 MHz) for special services video feeds for Woodbine Entertainment in the GTA. This spectrum in theory would otherwise lie fallow in the GTA. Outside the major urban areas, the upper 2 GHz band is available to low and medium capacity, point-to-point FS applications. So, it is only in the major urban areas where the paired spectrum at 2200-2285 MHz might be available for UBS. This would not satisfy their stated needs.

  • Agreement with the MHz (Arrangement D).
  • 2290-2300 US in this band
  • 2290-2300 MHz
  • General use of the band 2200-2285 MHz by P-MPT, particularly for ubiquitous applications of the UBS type in the access, could create compatibility problems with the space science services.

  2290-2300 MHz is currently used by Roger Wireless for fixed point-to-point. It is part of the old super 2 GHz band plan (revised by IC in 1995) covering 2290-2360/2520-2590 MHz

2290-2300 MHz (Government band) is used by NASA for deep space downlinks. Paired with 2110-2120 MHz in the uplink. Currently there is no agreement with the US in this band. TDRSS F1 – F7 uses 2211 MHz. F8 – F10 uses 2205 MHz specifically (TT&C operations (i.e. it is primarily used during L&EO, backup/emergency operations, TDRS stored operations)

In Canada, this 10 MHz is part of the "old" super 2 GHz band plan SRSP302.2 (1990), covering 2290-2350/2390- 2450 MHz. In 1995, the RABC prepared and recommended to IC a new super 2 GHz band SRSP 302.29 covering 2290 2360/2520-2590 MHz which was trying to find spectrum for P-P and P-MPT growth outside the licence-exempt spectrum 2400-2483.5 MHz. As we know, this new plan was not officially blessed by IC due to MCS developments but I believe that some FS stations were licensed under the RABC plan nevertheless.

FS microwave stations have been licensed under both SRSP302.2 and the RABC plan. Some of these stations may need to be turned down as a result of the policy provision in SP 2285 MHz (section 3.5) where, as of April 2002, the paired channels at 2390-2400 MHz is operating on a no-protection basis from MATS and a 1-year displacement provision if there is potential for interference to MATS.

ARNS future plans

Currently civil aviation radar coverage is achieved using L band radars, in 1215-1300 MHz, and also 1350-1370 MHz band. From a domestic standpoint we have not yet migrated to S band 2700-2900 MHz, but that is dependant on life cycle of the L band radars. At a later time, Nav Canada does plan to use S band radars, unfortunately, we do not know what the time frame will be. However, considering the geographical diversity involved, perhaps at that time we could work out specific channel assignments to avoid conflict with RA.

EC: McGill U radar part of the Canadian operational and research radar network

EC: US weather radar network providing critical data (e.g. storm development) upstream of Canadian populated areas
The band (2750-2800 MHz) has been used continuously for more than 50 years to measure the "10.7 cm Solar Radio Flux", which is used worldwide as a fundamental index of solar activity. The choice of frequency was fortuitous, but, although there is no formal allocation in this band for this service, we cannot change frequency, since it would raise questions as to data validity and consistency, which are factors upon which the international reputation of this Canadian service is based.

Canadian Footnotes

C8
Radio astronomy observations are carried out in the band 322–328.6 MHz and such operations will be protected from interference to the extent possible.
C49
In the bands 7 250-7 750 MHz and 7 900-8 400 MHz and, in all or a portion of, the bands 20.2- 21.2 GHz, 30-31 GHz and 39.5-40.5 GHz as required, the use of the fixed-satellite service is limited to the Government of Canada.

Radio Astronomy Notes

RA.0
This band is used for riometry, which is an application of radio astronomical techniques to study the ionosphere. A riometer, or relative ionospheric opacity meter, is a simple radio telescope, operating in the HF band, which measures the attenuation of radio emissions from the Milky Way due to their passage through the ionosphere. These devices are a powerful means of monitoring changes in the D-Region. DRAO is currently hosting a riometer owned by Natural Resources Calgary and there are plans to implement at DRAO at least one additional instrument, to be built by the University of Calgary.
RA.1
Canada is developing a prototype antenna for use in the Square Kilometer Array. This is an international project. The final instrument will not be in Canada, but prototype for one of the array elements, a 30-m dish, is planned for construction at DRAO. The SKA is intended for use up to K-Band. Timescale: 2010. The radio telescope will then be moved to a radio-quieter part of the DRAO site and be used as a research instrument.
RA.2
This frequency band is used 24 hours a day and every day apart from maintenance periods. The current survey could keep the instrument busy for at least another ten years, and other projects may continue indefinitely.
RA.3
On an opportunistic basis, observations of redshifted HI emissions are occasionally made at frequencies close below 1400 MHz, where there is no allocation to the Radio Astronomy Service. This note is not a request for an allocation change, but is included for information purposes.
RA.4
This band is used a few times each year in observing sessions on the 26m radio telescope. It is not used full time, so there are coordination and scheduling options available that are not available at 406-410 and 1420-1427 MHz.
RA.5
There are no plans to use this band for formal radio astronomy in Canada. However, this band will be one of those used by large arrays such as the Very Large Array, Socorro, New Mexico, in which Canada is in the process of buying a share. We will be providing the upgraded signal processing equipment the Americans need for their upgraded array, which involves sporadic test observations at DRAO. In return we will get guaranteed access for Canadian astronomers. Timescale: now.
RA.6
There are no plans to use this band in Canada. However, this band will be one of those used by large arrays under construction, such as ALMA, which is currently under construction in Chile. Canada is a major shareholder in this project. This instrument is regarded as a keystone project the Long-Range Plan for Canadian Astronomy. Timescale: 2008.
RA.7
This band is also used at the James Clerk Maxwell Telescope, on Mauna Kea, Hawaii. Canada is a stakeholder in this project. This instrument has been in full operation for some years, and will continue to be an important instrument to Canadian astronomers for at least another decade.
RA.8
This frequency band is one of those intended for use by the Next Generation Solar Flux Monitor, a joint project of the National Research Council, Natural Resources Canada, the Canadian Space Agency and Queen's University, which is now under construction at DRAO.

Natural Resources Canada is doing VLBI at the Algonquin Radio Observatory, in the Algonquin Provincial Park. This is a geophysics program using Very Long Baseline Interferometric techniques to study the distortion of North America due to plate motions. At the moment the program uses S and X band. There are dreams of doing broad-band VLBI over 2-15 GHz, obviously using some very exotic and partially undeveloped signal processing techniques. However, the broad-band transmitters are not likely to be in permanent operation close to ARO. (Text from K. Tapping Sept 6, 2005)

The Algonquin Radio Observatory is a research facility located at (45°57'19.81"N, 78°4'22.95"W) in the Algonquin Provincial Park in Ontario, Canada. The site houses a 46-m single-dish radio antenna, a solar-observing array of 32 three-meter dishes, and a single 1.8-m solar flux monitor observing at 10.7-cm wavelength. The large dish is involved in VLBI experiments, including geodesy. Begun in 1959, the Observatory is situated deep in Ontario's Algonquin Provincial Park, away from manmade interference. The site contains a collection of instruments designed for research in several phases of radio astronomy: an array of 32 parabolic reflectors, each 3 m in diameter, scans the face of the sun every noon; nearby, a single 1.8 m dish monitors the whole solar disk at a wavelength of 10.7 cm; standing above these is the giant 46 m dish, built in 1966, to study radio sources far out in space.

The Algonquin Radio Observatory's (ARO) 46 m telescope began operations in May, 1966. The telescope was built and operated by the National Research Council (NRC) of Canada. At the current time the ARO is operated by the Geodetic Survey Division of Natural Resources Canada in partnership with the Space Geodynamics Laboratory, CRESTech.
