Abstract : The paper describes the developmental system requirements for an S-band, single-frequency navigation method titled 'Rivers and Harbors Aid to Navigation System' (RIHANS). The system is sectionalized into two major parts termed (1) service segment covering all equipments needed for land-based operation and (2) the user segment covering all equipment needed for shipboard detection and display of navigation position. The detailed breakdown is defined in section 3, Functional Requirements, of this paper. The user segment is defined for two levels of cost with the difference attributed to user accuracy and method of display. The low cost user equipment will provide 125-feet accuracy and requires manual plotting of position while the automatic user equipment will provide an accuracy of 50 feet with automatic position indications.
