The GLONASS reception equipment designed for navigation on vessels with a maximum speed of 50 knots must meet the minimum operational requirements outlined in addition to the general provisions specified in resolution A.694(17).
The current standard establishes only the basic conditions required for navigation purposes and does not apply to other calculators that may be integrated into the hardware.
It is acknowledged that additional data inputs may be available, such as speed and distance indicators, gyrocompasses, or other navigation systems utilizing differential GLONASS corrections However, the minimum operational requirements outlined in this standard pertain solely to the use of signals from the specified sources.

RTCM recommended standards for differential GPS/GLONASS: 1996
For the purposes of this International Standard, all definitions and abbreviations used, are contained in the normative reference of the GLONASS ICD specification.
Receiver equipment for the Global Navigation Satellite System (GLONASS) used on ships with maximum speeds of 50 knots or less must meet specific minimum performance requirements, in addition to the general standards outlined in resolution A.694(17).
(53.66/1.4) This standard covers the basic requirements of position fixing for navigation purposes only and does not cover other computational facilities which may be in the equipment.
This standard acknowledges the potential inclusion of additional data inputs, such as speed and distance measuring equipment (SDME) and gyro or other navigational systems, including GLONASS differential corrections However, it emphasizes that the fundamental minimum performance standards specifically apply to the utilization of GLONASS signals solely for navigational position fixing.
Other computational activity, input/output activity or extra display functions shall not degrade the performance of the equipment below the minimum performance standards set out in this standard.
The receiver shall comply with the provisions of IMO Resolutions A.529, A.815, MSC.53(66),
A.694 and IEC 61162-1 and be tested in accordance with IEC 60945.

The term "GLONASS reception equipment" refers to all components and organs necessary for the system to perform its intended functions as outlined in the operational standard The equipment must include at least the following elements: an antenna capable of receiving GLONASS signals, a GLONASS receiver and processor, a means to obtain calculated position in latitude and longitude, data control and an interface, and a position display along with any additional output forms if required.
4.2.2 Le matériel peut être livré en une ou plusieurs configurations pour pouvoir fournir les informations de position nécessaires En voici quelques exemples:
– récepteur autonome avec dispositif d'accès par clavier à la position calculée, les informations relatives à la position s'affichant de manière appropriée;
– récepteur GLONASS alimentant un système intégré avec dispositif d'accès à la position calculée via une interface adéquate, les informations relatives à la position étant disponibles à au moins une station distante.
Les exemples ci-dessus ne sont pas destinés à prétendre que l'évolution future est limitée.
4.3 Normes de fonctionnement du matériel de réception GLONASS
(53.66/3.1.1) L'équipement de réception du système GLONASS doit pouvoir recevoir et traiter les signaux émis dans le cadre du service de positionnement normal (SPS) du système
GLONASS provides positioning information in the form of coordinates based on the Soviet geocentric system SGS-90 (PZ-90), expressed in degrees, minutes, and thousandths of minutes of latitude and longitude, along with the resolution time indicated in UTC(SU).
Des moyens doivent être prévus pour convertir la position calculée en fonction de l'ellipsọde
The SGS-90 (PZ-90) coordinates are compatible with the World Geodetic System (WGS-84) or the reference level of the utilized nautical chart When this conversion is possible, the receiver must indicate that the coordinate conversion is in progress and specify the coordinate system used to express the position.
The OMI resolution initially utilized SGS-90 as the reference level for the GLONASS system However, since the implementation of this resolution, the reference level has been updated to PZ-90 It is anticipated that the OMI resolution will be revised accordingly For further details, refer to sections 4.3.2, 5.3, 5.5.2, and 5.6.4.1.1.
(53.66/3.1.2) L'équipement de réception du système GLONASS doit fonctionner dans le cadre du service de positionnement normal (sur les fréquences L1 désignées par des lettres et avec le code C);
The resolution MSC.53(66) of the IMO states that the GLONASS equipment must operate on the L1 sub-band frequencies with a standard precision navigation signal The Russian Federation prefers this specific wording, and it is anticipated that the IMO resolution will be amended accordingly.
The GLONASS reception equipment must have at least one output to provide positional information to other devices The position data is obtained using the SGS-90 system (PZ-90).
WGS-84 doivent être transmises de la manière prévue dans la CEI 61162.
NOTE – Les messages qu'un récepteur de sortie GLONASS doit fournir sont décrits en détail dans la CEI 61162-1.

The term "GLONASS receiver equipment" encompasses all essential components required for the system to function effectively This equipment must include a capable antenna for receiving GLONASS signals, a GLONASS receiver and processor, a method for accessing computed latitude and longitude positions, data control and interface mechanisms, and a position display, along with any additional output forms as necessary.
4.2.2 The equipment may be supplied in one of several configurations to provide the necessary position information Examples are:
– stand-alone receiver with means of accessing computed position via a keyboard with the positional information suitably displayed.
– GLONASS receiver feeding an integrated system with means of access to the computed position via an appropriate interface, and the positional information available to at least one remote location.
The above examples should not be implied as limiting the scope of future development.
4.3 Performance standards for GLONASS receiver equipment
The GLONASS receiver must be capable of receiving and processing Standard Positioning Service (SPS) signals, providing position information in latitude and longitude using SGS-90 (PZ-90) coordinates It should also reference the time of solution to UTC (SU) and include means to convert the computed position into WGS-84 or compatible data for navigational charts Additionally, the display must indicate when coordinate conversion is taking place and specify the coordinate system used for the position.
NOTE – The IMO Resolution uses SGS-90 as the GLONASS datum Since the time of the adoption of that
Resolution the datum has been changed to PZ-90 It is assumed that the IMO Resolution will be amended accordingly (see also 4.3.2, 5.3, 5.5.2, and 5.6.4.1.1).
(53.66/3.1.2) The GLONASS receiver equipment shall operate on the Standard Positioning
Service (on lettered L1 frequencies and C code).
The Russian Federation proposes that the IMO Resolution MSC.53(66) be amended to specify that "The GLONASS receiver equipment shall operate on the L1-sub-band frequencies with the standard precision navigation signal." It is anticipated that the resolution will be updated to reflect this preference.
