Show SURVEY WORLD BY WIRELESS Scheme to Be Tested In Determining the Boundary Between 8outh and West Auitrslla. It Is proposed to utilize wireless telegraphy In determining the exact position of tho boundary between South nnd West Australia. The boundary bound-ary Is llxed by net of parliament ns the VJOth degree of longtltude east of Oreennlch. The exact position of the longtltudo will ho ascertained by tho use of time signals from n high power wireless station situated st some point bet wen Greenwich obserwi-lory, obserwi-lory, In England, mid Sydney, In Australia, Aus-tralia, the signals being received sl lnultaticously nt both stations. Most of the great observatories of tho world uro now collaborating In n redetermination of dm longitudinal division of the earth's surface by means of wireless time signals, and this Is one of the earliest uses of the system to settle a disputed position. Olven favorable static conditions, It has been found that signals from the I.jons wireless stutlun, In France, can he received In Australia ns well us nt Greenwich, and slgnnls from other stations, sta-tions, more favorably situated, nro also being tested, The eo-oporntlon of the United States as well ns tho, 21rltlt.li government tins been Invited. The scheme Is tlm first step toward n com-prehcnsUe com-prehcnsUe determination of tho whole longitudinal survey of Australia. |
