POTENTIAL PROBLEMS FOR USERS OF GPS RECEIVERS.
1. USERS OF GPS RECEIVERS ARE ADVISED OF POTENTIAL
PROBLEMS DUE TO GPS WEEK COUNTER ROLL OVER ON
06 APR 19.
2. THE GPS SYSTEM TRANSMITS TIME TO GPS RECEIVERS
USING A FORMAT OF TIME AND WEEKS AFTER THE START
DATE OF 06 JAN 80. THE DATA FIELD IN THE NAVIGATIONAL
MESSAGE SENT BY GPS SATELLITES CONTAINING THE NUMBER
OF WEEKS AFTER THE START DATE IS LIMITED TO A MAXIMUM
OF 1023 WEEKS.  WHEN THE GPS SYSTEM REACHES WEEK 1024,
THE SYSTEM WILL REVERT BACK TO WEEK ZERO.
3. SOME GPS RECEIVERS ARE KNOWN TO BE UNABLE TO MAKE
THE TRANSITION FROM WEEK 1023 TO 1024. IF THE GPS
RECEIVER IS OUTDATED OR LACKS PROPER UPDATES,
THE RECEIVER WILL REVERT TO READING THE WEEK ZERO
AS AUGUST 1999. DURING THIS TIME THE INTERNAL CLOCKS OF
THESE GPS RECEIVERS WILL EXPERIENCE A LACK OF ABSOLUTE
REFERENCE AND MAY GIVE THE WRONG TIME AND POSITION OR
MAY LOCK UP PERMANENTLY.
4. SOME OF THESE GPS RECEIVERS ARE REPAIRABLE WITH
UPGRADES AND OTHERS WILL BECOME UNUSABLE. USERS ARE
ADVISED TO CHECK WITH THEIR GPS MANUFACTURER REGARDING
THE STATUS OF THEIR RECEIVER.

DIFFICULTES EVENTUELLES POUR LES UTILISATEURS DE RECEPTEURS GPS.
1. LES UTILISATEURS DE RECEPTEURS GPS SONT AVERTIS D EVENTUELS
PROBLEMES RESULTANT DE LA REINITIALISATION DU COMPTEUR DE SEMAINES
DES GPS LE 06 AVRIL 2019.
2. DEPUIS SON LANCEMENT LE 06 JUIN 1980, LE SYSTEME GPS TRANSMET L
HEURE AUX RECEPTEURS GPS EN UTILISANT UN FORMAT HEURE-SEMAINE.
LE CHAMP DE DONNEES CONTENANT LE NUMERO DES SEMAINES DANS LES
MESSAGES ENVOYES PAR LES SATELLITES GPS EST LIMITE A UN MAXIMUM DE
1023 SEMAINES.
LORSQUE LE SYSTEME GPS ATTEINDRA LA SEMAINE 1024, LE SYSTEME
REVIENDRA A LA SEMAINE ZERO.
3. CERTAINS RECEPTEURS GPS NE SERONT PAS EN MESURE DE FAIRE LA
TRANSITION ENTRE LES SEMAINES 1023 ET 1024.
SI LE RECEPTEUR GPS EST OBSOLETE OU N A PAS EU LES MISES A JOURS
APPROPRIEES IL CONSIDERERA LA SEMAINE ZERO COMME ETANT AOUT 1999.
DURANT CETTE PERIODE, LES HORLOGES INTERNES DE CES RECEPTEURS
PERDRONT TOUTES REFERENCES ET POURRAIENT DONNER DES DATES ET DES
POSITIONS ERRONEES OU POURRAIENT SE VEROUILLER DE FACON DEFINITIVE.
4. CERTAINS DE CES RECEPTEURS GPS SERONT REPARABLES AVEC DES MISES A
JOUR, D AUTRES DEVIENDRONT INUTILISABLES.
IL EST CONSEILLE AUX UTILISATEURS DE S INFORMER AUPRES DES FABRICANTS
DE LEURS RECEPTEURS SUR L ETAT DE CES DERNIERS.
