A new analyze gave the following (http://phrio.biz/ccs/).
I posted a message to know how to use the BSP files, the answer is :
QuoteMr. ??? ,
I think you don't want an SPK file for a given small body; this is a complicated binary format requiring special software and knowledge to use.
Instead I suggest you try using this Horizon's webpage:
http://ssd.jpl.nasa.gov/horizons.cgi
You might also look at:
http://ssd.jpl.nasa.gov/?tools
Or use the telnet or email interface:
http://ssd.jpl.nasa.gov/?horizons#telnet
If you have further questions about generating/getting ephemerides for small bodies, it would be best to contact the Horizons folks.

That means :
I DON'T WANT TO HELP YOUNow I have created the datas for 200 asteroids and I must think of an other process design.
I have a lot of work and I don't where to begin!
I have a part of the answer.
The library CalcEph (http://www.imcce.fr/fr/presentation/equipes/ASD/inpop/calceph/index.html).
It is possible to use NASA kernels with it.
Here is an example
int _bRes ;
int j ;
double jd0 = 2415020.50 ; // 1-1-1900
double dt1 = 0.0 ;
t_calcephbin *pEph_1 ;
double PV[6] ;
/* open the ephemeris file */
pEph_1 = calceph_open("Ceres.bsp") ;
if(pEph_1)
{
memset(PV,0,sizeof(PV)) ;
_bRes = calceph_compute_unit(pEph_1,jd0,dt1,NAIFID_CERES,NAIFID_SUN,CALCEPH_USE_NAIFID+CALCEPH_UNIT_KM+CALCEPH_UNIT_SEC,PV) ;
/* close the ephemeris file */
calceph_close(pEph_1) ;
}
The results are

I generate a kernel here (http://ssd.jpl.nasa.gov/x/spk.html)
This kernel is heliocentric.
Now I have to test with DE430, DE431 and DE432 for having geocentric and topographic coordinates.
