and astronomic 



triangulatlon system 



Extended flaring system 



Many of the present and new 

 equipment and future develop- 

 ments do or will not require 

 extensive recording systems, 

 but many of the electronic 

 positioning systems will need 

 outputs compatible to elec- 

 tronic computers for rapid data 



Flexibility 

 Portability 

 Improved reliability
