The Nancay radiotelescope is involved in high precision timing since 20 years. Since 2004, a coherent dedispersion instrumentation enables numerous routine observations on more than 200 pulsars using half of the time of this 100-meters class radiotelescope. A set of highly stable millisecond pulsars is monitored as our contribution to the European Pulsar Timing Array in order to probe any kind of Gravitational Waves background. An encouraging first result was recently obtained (vanHaasteren, this proceedings).
