In order to service regulations concerning the upgrade of radiosondes, the Ministry of Internal Affairs and Communications (MIC) has drawn up a Ministerial Ordinance Plan for Partial Revision of Procedural Rules for Radio Station Licenses and a Directive Plan for Partial Revision of Radio Law-related Inspection Standards.
Accordingly, an appeal for opinions on the above-mentioned Ministerial Ordinance Plan and Directive Plan will be held from June 25 (Sat) to July 25 (Mon), 2011.
1. Outline
Radiosondes are a form of wireless equipment installed in balloons and aircraft, etc. carried to high altitude levels of the atmosphere to transmit meteorological information to the ground, including atmospheric temperature, humidity, pressure, wind direction, wind speed, etc.
Radiosondes are currently utilized in direct measurement of high altitude levels of the atmosphere for the high altitude meteorological observation necessary for weather forecasting, etc. However, in order to support diversified needs such as simultaneous observation of multiple sites and short time continuous observation, the Ministry of Internal Affairs and Communications (MIC) has carried out system maintenance so as to upgrade radiosondes, convert occupied frequency bandwidths to narrowband, and expand the frequencies that can be allocated.
This matter services the relevant regulations to facilitate the prevention of interference between relevant parties, i.e. by allocating frequencies according to the situation in which radiosondes are used, and so on.
2. Main contents to be revised
(1) In order to allocate frequencies taking into account the situation of radiosonde use when inspecting radio stations, this will be written in the recipient's field in the radio station item list in the document attached to the written application in the case of fixed observation .
(2) Frequencies allocated to narrowband radiosondes will be set as the 25 common use waves between 403.3MHz and 405.7MHz, and allocations will be made with the assumption that usage will be adjusted to prevent interference between relevant parties.
(3) Frequencies allocated to narrowband radiosondes will be allocated according to whether or not the radiosonde is in a fixed observation situation.
