지구정지궤도는 위성통신과 방송을 위한 필수요소로서 ITU 체제가 그 관리의 중심이다. ITU체제는 지구정지궤도를 이용하고자 하는 주관청의 사전신청 및 조정 의무를 규정하고 있으며, ITU 사무국과 RRB는 등록원부 등재 및 삭제를 통해서 정지궤도 이용권을 관리하고 있다. 등록원부에 등재된 위성망 정보는 관련 주관청과의 조정의 결과에 따라서 그 지위가 달라진다. ITU 무선규칙은 위성망 정보를 등재한 주관청이 실제로 위성을 운용하는가의 여부에 따라서 등재정보가 삭제 또는 변경되도록 하여 지구정지궤도가 필요한 주관청이 실질적으로 사용할 기회를 보장하고 있다. 그러나 위성망을 신청하는 주관청 국가의 국적과 지구정지궤도에서 실제로 운용되는 인공위성의 국적이 같아야 한다는 규정이 없으며, 또한 위성망을 신청한 주관청 국가와 인공위성간의 연결관계에 관한 규정도 없고, 주관청과 위성망 소유 기업간의 연결 관계에 관한 규정도 없다. 이러한 상황에서 지구정지궤도를 둘러싼 분쟁은 사실상 주관청만이 아니라 기업이 등장하는 조정을 통해서 해결되고 있다. 그 결과는 위성 궤도를 거래하는 사실상의 이차 시장의 등장이다. 이차 시장의 존재는 기존의 ITU 무선규칙 및 사무국과 RRB의 역할에 따른 제도적 틀의 한계를 입증한다. 예컨대 RRB는 제13.6조를 적용하지 않기로 결정하고, 당사자간의 조정을 촉구하는 것으로 자신의 업무를 한정한 바 있고, 주관청간의 위성망 거래가 합법임을 사실상 인정하고 있다. ITU의 무선규칙상 또한 RRB의 방침상 인공위성과 궤도의 그러한 거래는 위법이 아니다. 무궁화위성 3호의 국적이 대한민국이더라도 홍콩 소재 기업이 다른 주관청과 합의하여 그 주관청 명의의 위성망 신청하에 무궁화 위성 3호를 사용하고 있다의 증거로 사용할 수 있다. 무궁화 위성 3호의 매각이 국내법 위반이어서 매각계약 자체가 무효라 하더라도 마찬가지이다. 이제 동경 116도의 Ka 밴드 이용권은 ITU가 주관하는 분양시장이 아니라 ITU가 등기소 역할만을 하는 장외시장에 나온 매물이다.

Situated close to Heathrow Airport, and adjacent to the M4 and M25 Motorways, the site at Axis Park is considered a prime location for business in the UK. In consequnce two of the UK's major property development companies, MEPC and Redrew Homes sought the expertise of Intergeo to remediate the contaminated former industrial site prior to its development. Industrial use of the twenty-six hectare site, started in 1936, when Hawker Aircraft commence aircraft manufacture. In 1963 the Firestone Tyre and Rubber Company purchased part of the site. Ford commenced vehicle production at the site in the mid-1970's and production was continued by Iveco Ford from 1986 to the plant's decommissioning in 1997. Geologically the site is underlain by sand and gravel, deposited in prehistory by the River Thames, with London Clay at around 6m depth. The level of groundwater fluctuates seasonally at around 2.5m depth, moving slowly southwest towards local streams and watercourses. A phased investigation of the site was undertaken, which culminated in the extensive site investigation undertaken by Intergeo in 1998. In total 50 boreholes, 90 probeholes and 60 trial pits were used to investigate the site and around 4000 solid and 1300 liquid samples were tested in the laboratory for chemical substances. The investigations identified total petroleum hydrocarbons in the soil up to 25, 000mg/kg. Diesel oil, with some lubricating oil were the main components. Volatile organic compounds were identified in the groundwater in excess of 10mg/l. Specific substances included trichloromethane, trichloromethane and tetrachloroethene. Both the oil and volatile compounds were widely spread across the site, The specific substances identified could be traced back to industrial processes used at one or other dates in the sites history Slightly elevated levels of toxic metals and polycyclic aromatic hydrocarbons were also identified locally. Prior to remediation of the site and throughout its progress, extensive liaison with the regulatory authorities and the client's professional representatives was required. In addition to meetings, numerous technical documents detailing methods and health and safety issues were required in order to comply with UK environmental and safety legislation. After initially considering a range of options to undertake remediation, the following three main techniques were selected: ex-situ bioremediation of hydrocarbon contaminated soils, skimming of free floating hydrocarbon product from the water surface at wells and excavations and air stripping of volatile organic compounds from groundwater recovered from wells. The achievements were as follows: 1) 350, 000m3 of soil was excavated and 112, 000m3 of sand and gravel was processed to remove gravel and cobble sized particles; 2) 53, 000m3 of hydrocarbon contaminated soil was bioremediated in windrows ; 3) 7000m3 of groundwater was processed by skimming to remove free floating Product; 4) 196, 000m3 of groundwater was Processed by air stripping to remove volatile organic compounds. Only 1000m3 of soil left the site for disposal in licensed waste facilities Given the costs of disposal in the UK, the selected methods represented a considerable cost saving to the Clients. All other soil was engineered back into the ground to a precise geotechnical specification. The following objective levels were achieved across the site 1) By a Risk Based Corrective Action (RBCA) methodology it was demonstrated that soil with less that 1000mg/kg total petroleum hydrocarbons did not pose a hazard to health or water resources and therefore, could remain insitu; 2) Soils destined for the residential areas of the site were remediated to 250mg/kg total petroleum hydrocarbons; in the industrial areas 500mg/kg was proven acceptable. 3) Hydrocarbons in groundwater were remediated to below the Dutch Intervegtion Level of 0.6mg/1; 4) Volatile organic compounds/BTEX group substances were reduced to below the Dutch Intervention Levels; 5) Polycyclic aromatic hydrocarbons and metals were below Inter-departmental Committee for the Redevelopment of Contaminated Land guideline levels for intended enduse. In order to verify the qualify of the work 1500 chemical test results were submitted for the purpose of validation. Quality assurance checks were undertaken by independent consultants and at an independent laboratory selected by Intergeo. Long term monitoring of water quality was undertaken for a period of one year after remediation work had been completed. Both the regulatory authorities and Clients representatives endorsed the quality of remediation now completed at the site. Subsequent to completion of the remediation work Redrew Homes constructed a prestige housing development. The properties at "Belvedere Place" retailed at premium prices. On the MEPC site the Post Office, amongst others, has located a major sorting office for the London area. Exceptionally high standards of remediation, control and documentation were a requirement for the work undertaken here.aken here.
